Heat is the thermal energy transferred between a system because of a temperature difference between them. The SI unit of heat is Joules .
For an object having mass , specific heat capacity
, and change in final and initial temperature as
.
Fahrenheit , Celsius
, and kelvin is mostly used to measure the temperature.
The conversion formula used to convert between Fahrenheit and degree centigrade.
If denotes the kelvin temperature, and
denotes the Celsius temperature.
Two bodies , and
are said to be in thermal equilibrium if no heat transfer takes place when they are placed in contact with each other.
It is denoted by , and it is the amount of energy needed to raise the temperature of
of a substance by
.
Material | Specific Heat | Specific Heat | Specific Heat Capacity |
Water | 4186 | 4200 | 1 |
Ice | 2090 | 2100 | 0.530 |
Aluminum | 900 | 900 | 0.215 |
Copper | 387 | 400 | 0.0923 |
Question 1: We have of hot water with a temperature of
. After few moments, the temperature was
. How much thermal energy has been transferred from the system?
Explanation: We have given mass, initial and final temperature, let us apply the formula.
So,
And, we have ,
,
. Also, Specific heat for water would be
.
Rewrite the mass
Plug the values
Final answer: So, there were of energy has been transferred to surrounding due to cooling.
Question 2: A copper block with a mass of 1.5 kg is heated from to
. Calculate the energy required to heat the block.
Explanation: We have given mass, initial and final temperature. So,
And, we have ,
,
. Also, Specific heat for water would be
.
Plug the values
Final answer: The energy required to heat the block would be .
Question 3: A metal ball with a mass of 2 kg, is heated to , it requires
to heat the ball, identify the metal using specific heat capacity.
Explanation: We have given mass, change in temperature, energy used. So,
We have , and
Plug the values.
Final answer: The calculated specific capacity of metal is close to the specific heat capacity of Aluminium. So, the metal used would be Aluminium.

Heat as the flow of energy from a warm object to a cooler object is known as heat.
Heat is thermal energy transferred from a hotter object to a cooler object thats are in contact with each other. Temperature is the average kinetic energy of the atoms or molecules that are in the system.
Yes heat produces more heat.Heat is produced by matter. Matter is made up of atoms and molecules and energy causes the atoms and molecules to always be in motion.
Heat is the form of energy that is transferred between the systems or objects with different temperatures,or levels.
Heat is the transfer of kinetic energy from one medium to another medium . This type of energy transfer is of three ways: radiation, conduction, and convection.
Heat can be transferred in three ways: by conduction, by convection, and by radiation
a. Conduction is the transfer of energy from one molecule to another by direct contact.
B. Convection is the movement of heat by a fluid such as water or air.
C. Radiation is the transfer of heat by electromagnetic waves
