50 g of copper is heated to increase its temperature by `10^@C`. If the same quantity of heat is given to `10g` of water, the rise in its temperature is (specific heat of copper`=420J//kg^(@)//C`)

A

`5^@C`

B

`6^@C`

C

`7^@C`

D

`8^@C`

Text Solution

Verified by Experts

The correct Answer is:
A
Same amount of heat is supplied to copper and water, so
`m_(c)c_(c)DeltaT_c=m_omegac_omegaDeltaT_omega`
`implies(DeltaT)_omega=(m_(c)c_cDeltaT_c)/(m_omegac_omega)=(50xx10^-3xx420xx10)/(10xx10^-3xx4200)=5^@C`

Certain amount of heat is given to 100 g of copper to increase its temperature by 21^@C . If same amount of heat is given to 50 g of water, then the rise in its temperature is (specific heat capacity of copper = 400 J kg^(-1) K^(-1) and that for water = 4200 J kg^(-1) K^(-1))

420 J of energy supplied to 10g of water will rises its temperature by

Some heat energy is given to 120 g of water and its temperature rises by 10 K. When the same amount of heat energy is given to 60 g of oil, its temperature rises by 40 K. The specific heat capacity of water is 4200 J kg- K^(-1) . Calculate : (i) the amount of heat energy in joule given to water, and (ii) the specific heat capacity of oil.

200 g of water is heated from 40^(@)C "to" 60^(@)C . Ignoring the slight expansion of water , the change in its internal energy is closed to (Given specific heat of water = 4184 J//kg//K ):

A copper ball of mass 100 gm is at a temperature T. It is dropped in a copper calorimeter of mass 100 gm, filled with 170 gm of water at room temperature. Subsequently, the temperature of the system is found to be 75^(@)C . T is given by : (Given : room temperature = 30^(@)C , specific heat of copper =0.1 cal//gm^(@)C )

Water of mass m_(2) = 1 kg is contained in a copper calorimeter of mass m_(1) = 1 kg . Their common temperature t = 10^(@)C . Now a piece of ice of mass m_(2) = 2 kg and temperature is -11^(@)C dropped into the calorimeter. Neglecting any heat loss, the final temperature of system is. [specific heat of copper =0.1 Kcal//kg^(@)C , specific heat of water = 1 Kcal//kg^(@)C , specific heat of ice = 0.5 Kcal//kg^(@)C , latent heat of fusion of ice = 78.7 Kcal//kg ]
