Can something get hotter than the thing heating it?

Can something get hotter than the thing heating it?

Heating a fuel/oxidizer mixture in air can eventually cause combustion of the mixture that results in it getting hotter than the original source. Otherwise net energy flow always goes from the hotter to the cooler object, and the cooler object can’t get warmer than the system that heats it.

Is it possible for an object to be hotter than another object if they are at same temperature?

An object is hotter than another if they are at same temperature but if the temperature of one object is higher than that of the other object, there will be transfer of energy from the hotter to the colder object until both objects reach the same temperature.

What happens to objects if they are exposed to heat?

Heat Changes the Temperature of Objects First, it changes the temperature of an object. Heat, once absorbed as energy, contributes to the overall internal energy of the object. One form of this internal energy is kinetic energy; the particles begin to move faster, resulting in a greater kinetic energy.

What causes something to heat up or cool down?

Over time, there will be a flow of energy from the hotter object to the cooler object. This flow of energy is referred to as heat. The heat flow causes the hotter object to cool down and the colder object to warm up.

Can a pan get hotter than the oven?

At best it will keep the air warm so that it is easier to keep the pot heated to 400 degrees. But since the stove will only ever make the outside of the stove warm, not above 400 degrees, the pot will also never be able to go above that. If the pot is exposed to a net energy gain its temperature will rise above 400.

How hot can an object get?

But what about absolute hot? It’s the highest possible temperature that matter can attain, according to conventional physics, and well, it’s been measured to be exactly 1,420,000,000,000,000,000,000,000,000,000,000 degrees Celsius (2,556,000,000,000,000,000,000,000,000,000,000 degrees Fahrenheit).

How can one object feel warmer than?

READ ALSO:   What is enthalpy in simple words?

how can one object feel warmer than another object if the two objects are at the same temp? The object that is a better conductor of heat feels cooler to the touch because it conducts heat away from the hand faster.

How do we decide which object is hotter than the other object explain?

We can find that one object is hotter than other by touching. This is because we have sensory tissues in our hands which react to temperature. We often decide it by touching the objects, in the case of a hot body, heat flows into our body while in case of a cold body heat flows out of our body.

Do things cool or heat faster?

Heating is not faster than cooling. We just have easier access to really hot stuffs compared to really cold stuffs. Higher the temperature difference, the more efficient is the heat transfer, meaning you transfer heat with less waste and in less time.

Do things get colder or hotter faster?

Observations. As a general rule, the rate at which a hot object changes temperature (cools down) cannot be stated to be faster (or slower) than the rate at which a cold object changes temperature (heats up).

What happens to an object when it is heated?

When an object is heated, its particles move more vigorously and its internal energy increases. Unless the object changes state (eg melts or boils), its temperature will increase. A swimming pool at 30°C is at a lower temperature than a cup of tea at 80°C.

What happens when two objects are at the same temperature?

If you have two objects or substances that are different temperatures, heat will always move OUT of the warmer object or substance, and INTO the cooler object or substance. This heat transfer will continue until the objects are the same temperature.

Can a gas bubble become hotter than its heat source?

An experiment on board the MIR spacecraft showed that a bubble of SF 6 gas (above, surrounded by SF 6 liquid and two temperature sensors) can become hotter than its heat source in the surrounding walls. When you heat soup on the stove, you don’t expect it to get hotter than the burner because heat normally flows from hot regions to cold ones.

How does heat travel through materials?

Conduction is how heat travels between objects that are touching. Conduction travels fastest through solids, but liquids and gases can also conduct heat. Some materials, like metal, can conduct heat very quickly, while other materials (like plastic or wood) conduct heat very slowly.
