Answer:
2kcal
Explanation:
heat=mass×rise in temperature×specific heat capacity
specific heat capacity of water =1 cal/J°
rise in temperature =40-0=40°C
mass=50g
heat =50×1×40
heat=2000Cal
heat=2kcal

Answer:
hey mate here is your answer ❤️
when ice is at 0° C temperature and we now rise the temperature , ice melts and forms water.
here in question, we have require to find the amount of heat required to convert 50gm of cake at 0°C to water at 0°C.
use, Heat = mlf
here, m is mass of ice and is latent of fusion.
basically latent heat of fusion of ice = 80cal/gm
so, Heat = 50gm × 80cal/gm
= 4000cal
