Question

2000 cal of heat is supplied to 200 g of water. Find the rise in temperature. (Specific heat of water = 1 cal /g °c)

Open in App

Solution

given , m=200g,Q=2000cal,Δθ=?, , specific heat of water c=1cal/g °cNow , heat required to raise the temperature of water is given by the definition of specific heat ,
Q=m c Δθ
or Δθ=Q/(m c)
=2000/(200×1)
=10°C

and the heat supplied to it. Find its mass and specific latent heat of fusion. Also find the specific heat capacity of the body in its liquid state.

Q. 1 kg of water is supplied 630 kJ of energy. Specific heat of water is 4200 J/kg

^{\circ} C

.So calculate the rise in temperature of 1 kg water.

Steam at $100^{o} C$ is passed into 1.1 kg of water contained in a calorimeter of water equivalent 0.02 kg at $15^{o} C$ till the temperature of the calorimeter and its contents rises to $80^{o} C .$ The mass of the steam condensed in kg is

latent heat of vaporization of water = $540 c a l k g^{-} 1$ , specific heat capacity of water = $10^{3} c a l k g^{-} 1^{\circ} C^{-} 1$

1 kg

of ice at

- 10^{\circ} C

is mixed with

4.4 kg

of water at

30^{\circ} C

. The final temperature of mixture is

Given specific heat of ice

= 0.5 {cal/g}^{\circ} C

,
Specific heat of water

= 1 {cal/g}^{\circ} C

,
Latent heat of fusion for ice

= 80 cal/g

Q. A calorimeter contains

400 g

of water at a temperature of

5^{\circ} C

. Then,

200 g

of water at a temperature of

+ 10^{\circ} C

and

400 g

of ice at a temperature of

- 60^{\circ} C

are added. What is the final temperature(in

^{o} C

) of the contents of the calorimeter? Specific heat capacity of water

= 1000 c a l / k g / K

. Specific latent heat of fusion of ice

= 80 \times 1000 c a l / k g

. Relative specific heat of ice

= 0.5
