Question

using words from the word boxes below, complete the paragraph about heat transfer. there are three key ways that heat transfers. with objects, heat transfers when the objects come into direct contact. this is known as conduction. liquids and gases are different. because these two states of matter flow, or are fluid, dense particles rise and cooler, less dense particles sink. this ongoing process is known as convection. heat can also be transferred through space (distance) in the form of waves. this process is known as radiation. all objects give off, or emit, some heat. heat is a form of energy. the particles of an object vibrate, the faster the object is, the more heat it has. heat is always happening. heat always flows in the same direction: from hot to cold. because particles of an object are always moving, heat transfer will stop once two objects reach the same temperature. this is known as equilibrium. caused by particles in an object that vibrate, absorb, and emit energy, heat transfer happens when there is a temperature difference between two objects.

Explanation:

Heat transfer occurs in three main ways: conduction (through direct contact), convection (in fluids where warmer, less - dense particles rise and cooler, denser particles sink), and radiation (transfer of heat as electromagnetic waves). Heat always flows from warmer to colder areas and stops when thermal equilibrium is reached. All objects emit some heat in the form of energy.

Answer:

There are three key ways that heat transfers. With objects, heat transfers when the objects come into direct contact. This is known as conduction. Liquids and gases are different. Because these two states of matter flow, or are fluid, warmer, less - dense particles rise and cooler, denser particles sink. This ongoing process is known as convection. Heat can also be transferred through space (distance) in the form of radiation. All objects give off, or emit, some heat. Heat is a form of energy. Because particles of an object are always moving, heat is always happening. Heat always flows in the same direction: from warmer to cold. The particles of an object vibrate, the faster the particles of an object vibrate, the higher the temperature. Heat transfer will stop once two objects reach the same temperature. This is known as equilibrium.
