Question

Which one of the following shows the highest value of specific heat?
1. Alcohol
2. Methane
3. Kerosene
4. Water

Answer 1

Correct Answer - Option 4 : Water

The correct answer is Water.

• The amount of heat required to increase the temperature of one gram of a substance by one degree Celsius is referred to as specific heat.
• Among all the four given liquids that is kerosene, Methane, alcohol and water, only water has the highest specific heat.
• The value of specific heat of water is 4.18 Joules per gram. 
• The SI unit of specific heat capacity is Joule per Kelvin per Kilogram, J⋅kg⁻¹⋅K⁻¹.

 

•  Specific heat of Kerosene, Methane and alcohol are 2.01, 2.47 and 2.57 joules per gram respectively.
