Question

Difference between Heat and Temperature.​

Answer 1

Answer:

The heat of an object is the total energy of all the molecular motion inside that object.

Temperature is the measure of the thermal energy or average heat of the molecules in a substance.

SI Unit: Joule KelvinUnit Joules, Calories

Fahrenheit, Celsius, Kelvin

Symbol: Q T

Particles: It’s a measure of the number of atoms multiplied by the energy possessed by each atom. It is like a level which determines the direction in which the heat will flow. It is related to how fast the molecule within a substance are moving.

Answer 2

☆ Difference between Heat and Temperature :

★ Heat ★

➹ Heat is that form of energy which flows from a hot body to a cold body when they are kept in contact.

➹ The S.I. unit of heat is Joule (J).

➹ The amount of heat contained in a body depends on mass, temperature and substance of body

➹ Heat is measured by the principle of calorimetry.

➹ Two bodies having some quantity of heat may differ in their temperature.

➹ When two bodies are placed in contact, the total amount of heat is equal to the sum of heat of individual body.

━━━━━━━━━━━━━━━━━

★ Temperature ★

➹ Temperature is a quantity which determines the direction of flow of heat on keeping the two bodies at different temperatures in contact.

➹ The S.I. unit of temperature is Kelvin (K).

➹ The temperature of a body depends on the average kinetic energy of its molecules due to their random motion.

➹ Temperature is measured by a thermometer.

➹ Two bodies at same temperature may differ in the quantities of heat contained in them.

➹ When two bodies at different temperatures are placed in contact, the resultant temperature is a temperature in between the two temperatures.
