Which method of heat transfer can take place if two objects at different temperatures?

Which method of heat transfer can take place if two objects at different temperatures?

Convection
Convection is another way that heat can be transferred. Convection is motion in a gas or liquid that is caused by temperature differences. This motion transfers heat throughout the gas and liquid. The molecules in liquids and gases are farther apart and have more room to move around than in solids.

What happens when two objects at different temperature are in contact with one another?

If two objects at different temperatures are brought in contact with each other, energy is transferred from the hotter object (that is, the object with the greater temperature) to the colder (lower temperature) object, until both objects are at the same temperature.

Which method of heat transfer occurs when two objects or substances are in direct contact?

Conduction
Conduction is the transfer of heat between substances that are in direct contact with each other. The better the conductor, the more rapidly heat will be transferred. Metal is a good conduction of heat. Conduction occurs when a substance is heated, particles will gain more energy, and vibrate more.

What term is defined as the energy transferred between objects with different temperature?

define heat. the energy transferred between objects because of different temperatures.

What is needed for heat to transfer from one object to another the two objects should?

What is needed for heat transfer to take place is a difference in temperature between two objects. Heat can be transferred in three ways: by conduction, by convection, and by radiation. Conduction is the transfer of energy from one molecule to another by direct contact.

How does heat interact with different object?

When you bring two objects of different temperature together, energy will always be transferred from the hotter to the cooler object. The objects will exchange thermal energy, until thermal equilibrium is reached, i.e. until their temperatures are equal. Two objects of different temperature always interact. …

What is not a good thermal insulator?

Materials that are good conductors of thermal energy are called thermal conductors. Metals are very good thermal conductors. Materials that are poor conductors of thermal energy are called thermal insulators. Gases such as air and materials such as plastic and wood are thermal insulators.

What must be true if energy is to be transferred as heat between two bodies in physical contact?

What must be true if energy is to be transferred as heat between two bodies in physical contact? The two bodies must have different volumes. The two bodies must be at different temperatures. The two bodies must have different masses.

Will heat transfer if the temperature of two objects is the same class 7?

Ans. Heat will not be transferred if the temperature of two objects is the same.

What is needed for heat to transfer from one object to another the two object should?

What direction is heat transferred in the situation?

And unless people interfere, thermal energy — or heat — naturally flows in one direction only: from hot toward cold. Heat moves naturally by any of three means. The processes are known as conduction, convection and radiation. Sometimes more than one may occur at the same time.

How is heat transferred from one thing to another?

This is called heat transfer. (Remember, we learned that energy transfer is when energy moves from one thing or place to another, but the energy type stays the same). Heat can transfer (or move) in 3 ways: conduction, convection, and radiation.

Which is the fastest way for heat to travel between objects?

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.

How is convection related to the transfer of heat?

Some materials, like metal, can conduct heat very quickly, while other materials (like plastic or wood) conduct heat very slowly. Convection is how heat travels through fluids – liquids and gases. Hot fluids rise up, while cold fluids sink down. This up-and-down motion is called a convection current.

Which is an example of heat conduction between two objects?

There are many examples of heat conduction. Any time two object touch, heat conduction will happen. Touching a hot iron is an example of conduction – the heat passes out of the iron and into your hand. So is holding an ice cube – the heat is conducted out of your hand, and into the ice cube (that’s why your hand feels cold).
