Boiling is the rapid vaporization of a liquid, which occurs when a liquid is heated to its boiling point, the temperature at which the vapour pressure of the liquid is equal to the pressure exerted on the liquid by the surrounding atmosphere.

Although, some bacterial spores not typically associated with water borne disease are capable of surviving boiling conditions (e.g. clostridium and bacillus spores), research shows that water borne pathogens are inactivated or killed at temperatures below boiling (212°F or 100°C).

Is boiling water convection or conduction? Well, it is conduction through convection within the water. The water molecules are free to move around and thus form convection currents and try to bring the water to a uniform temperature.

When a raw egg begins to fry as it hits a heated frying pan, energy from the pan moves to the egg and cooks it. Why is this conduction? Heat is transferred through solids from one particle to another particle or from the pan to the egg. … It is not radiation because heat is not transferred through empty space.

Overview of Convection In Boiling Water These molecules produce kinetic energy. The hot water molecules become less dense, and they rise above the denser cooler molecules. This movement of molecules creates convection currents. Boiling water is an example of forced convection.

Radiation is considered the fastest mode of heat transfer as it travels as fast as light. Conduction is considered the slowest mode of heat transfer as it moves from particle to particle. natural Convection transfers heat over a distance faster than conduction but lower than radiation .

Radiation

Radiation can take place in vacuum too as radiation do not require any material medium for transfer of heat. It takes place by electromagnetic waves.

Various heat transfer mechanisms exist, including convection, conduction, thermal radiation, and evaporative cooling.

When a solid is heated the particles gain energy and start to vibrate faster and faster. Further heating provides more energy until the particles start to break free of the structure. Although the particles are still loosely connected they are able to move around. At this point the solid is melting to form a liquid.

Radiation heat transfer is the mode of transfer of heat from one place to another in the form of waves called electromagnetic waves. Some common examples of Radiation are Ultraviolet light from the sun, heat from a stove burner, visible light from a candle, x-rays from an x-ray machine.

Our body needs heat to survive life. We can die without heat.

Believe it or not, cold does not actually exist. What you’re experieincing when you experience cold, is the absence of heat. Temperature is the energy of clashing atoms. A cubic meter of deep space would make you freeze instantly due to the lack of atoms.

I lived without heat for an entire winter—here are my top tips for staying warm

1. Reverse the ceiling fans.
2. Choose your space heater wisely.
3. Cook in the oven as much as possible.
4. Use a humidifier.
5. Close off rooms that you aren’t using.
6. Open and close your curtains at the right time of the day.

Without the Sun’s warmth, Earth would quickly become a much colder place. Fortunately, Earth retains heat fairly well, so humans wouldn’t freeze instantly. Life would get much more difficult immediately, though. Without the Sun’s rays, all photosynthesis on Earth would stop.

With no sunlight, photosynthesis would stop, but that would only kill some of the plants—there are some larger trees that can survive for decades without it. Within a few days, however, the temperatures would begin to drop, and any humans left on the planet’s surface would die soon after.

There would be no power to use your fridge or freezer, telephone lines would be down and phone signal lost. Your mobile phones will be useless as the battery dwindles, with no back up charging option. Your gas central heating won’t work and your water supply would soon stop pumping clean water.

It is the pull of the Moon’s gravity on the Earth that holds our planet in place. Without the Moon stabilising our tilt, it is possible that the Earth’s tilt could vary wildly. It would move from no tilt (which means no seasons) to a large tilt (which means extreme weather and even ice ages).

The Moon also holds Earth’s 23.5-degree tilt fairly steady. Without that steadying hand, Earth would wobble much more, dramatically affecting the planet’s seasons and climate. The change in Earth’s tilt would happen gradually, though, so we wouldn’t notice it instantly or likely even within our lifetime.

Without a moon the tilt of our earth’s axis would vary over time. This could create some very wild weather. Right now, thanks to our moon, our axis stays tilted at twenty-three point five degrees. But without the moon the earth might tilt too far over or hardly tilt at all leading to no seasons or even extreme seasons.

The outer layers of the Sun could reach all the way to the Earth. This would slow the Moon down, sending it falling towards the Earth. As it gets closer to the Earth it would start ripping apart, before crashing into the Earth. In either case, an exploding Moon, by natural means at least, is pretty unlikely for now.

What if we all jumped at once? Because people are spread somewhat equally around the planet’s spherical surface , if we all jumped in place, nothing much would happen — all our lift-offs and impacts would cancel each other out, resulting in zero net force on the Earth, according to work by physicist Rhett Allain.

NASA cameras have captured video of the largest explosion it has ever seen on the moon… ‘For about one second, the impact site was glowing like a fourth magnitude star,’ NASA said. The meteoroid was traveling around 56,000 miles per hour when it slammed into the moon’s surface.

If the Earth stopped spinning suddenly, the atmosphere would still be in motion with the Earth’s original 1100 mile per hour rotation speed at the equator. This means rocks, topsoil, trees, buildings, your pet dog, and so on, would be swept away into the atmosphere.

If the Earth stopped spinning suddenly, most people on Earth would die. If the Earth slowed down gradually, it would be absolutely devastating, but there is a chance some people could survive.

Earth isn’t likely to ever get tidally locked to the sun — we’re too far away for that to happen. And, though our planet’s rotation is slowing down ever so slightly (a day gets about 1.7 milliseconds longer every century), our planet should never stop spinning completely.

The Moon is very big, and any small object hitting it would have very little effect on its motion around the Earth, because the Moon’s own momentum would overwhelm that of the impact. Most asteroid collisions would result in large craters and little else; even the largest asteroid known, Ceres, wouldn’t budge the Moon.

If the comet is 10 kilometers across or larger (that is, if the impact carries an energy of more than about 100 million megatons), the resulting global environmental damage will be so extensive that it will lead to a mass extinction, in which most life forms die.
