Question

10 g of water at 25°C was provided 50 calories of heat energy. The temperature of water increases by

Answer 1

Answer:

calorie: 1 calorie will raise 1 gram of water 1 degree Celsius. If 1 g of water is given 2 calories, its temperature will go up 2 degrees. Melting ice at 0 degrees Celsius: It takes 80 calories to melt 1 gram of ice.

Answer 2

ANSWER ::

The temperature of water increases by 5°C

EXPLANATION ::

Let T be the final temperature

Niw

m = mass= 10

s-specific heat capacity

∆t = Change in temperature = T - 25

We know that

Q=ms∆t

50 =10×1×(T -25)

T-25 = 5

T = 30

So Final temperature = 30°C

So The temperature of water increases by

= 30°C - 25°C = 5°C
