• calorie

• J

• kilo-calorie

• erg

What is the SI unit of specific heat capacity

• 
  $J\ kg^{-1^{ }}$ $K^{-1}$
  

• $Jg^{-1}$ $K^{-1}$

• $JK^{-1}$

• $J^0$ $C^{-1}$

What is the SI unit of  heat capacity

• 
  $J\ kg^{-1^{ }}$ $K^{-1}$
  

• $Jg^{-1}$ $K^{-1}$

• $JK^{-1}$

• $J^0$ $C^{-1}$

A calorimeter is made of copper because

• copper is a good conductor of heat

• copper has high specific heat capacity

• copper has low specific heat capacity

• Both option 3 and 1

• convection

• radiation

• All of these

How is convection prevented in calorimeter?

• Using wool and cotton in space between wooden jacket.

• Using a thermometer and stirrer

• Using copper vessel for mixing cold and hot objects

• Using a wooden lid with very small holes to cover it.
