Question

Thermal energy from a hot body flows to a cold body in the form of

(a) sound (b) signals (c) heat (d) waves​

Answer 1

Answer:

Heat energy , in radiation mode of transmission , lies in infrared region of electromagnetic spectrum . As infrared rays being electromagnetic waves , are transverse waves , so heat energy travels in the form of transverse waves .

Answer 2

Answer:

The correct option is C) heat.

Explanation:

• Thermal energy, also known as heat, naturally travels only one way: from hot to cold.
• Any one of three ways is how heat naturally transfers.
• The terms for the processes are radiation, convection, and conduction. At times, several could happen simultaneously.
• Without any real movement of the body's molecules, heat is transmitted from the hotter to the cooler parts of a body through a process known as conduction.
• A region with a higher temperature converts heat into a region with a lower temperature in liquids and gases.
• Convectional heat transfer is caused in part by the mass transfer or by the movement of molecules.

Heat is the form in which thermal energy flows.
