Calculate the amount of heat released when 50 g of steam at 100 celsius hits the skin condenses and cools to a body temperature of 37 celsius?

Answer 1

water's specific heat is 1 calorie/mL/degree celsius.

if you assume the density is 1 g/mL then we have 50 mL of material going from 100 to 37 degrees C.

So take Mass X Change in Temp X Specific heat and that is your answer.

Answer 2

To calculate the amount of heat released, you need to consider two processes: (1) The steam releasing heat as it cools from 100°C to 100°C water, and (2) The water releasing heat as it cools from 100°C to 37°C. The heat released during each process can be calculated using the specific heat capacity of water (4.184 J/g°C) and the heat of vaporization of water (2260 J/g). Once you calculate both heats, you can sum them up to determine the total amount of heat released.

Answer 3

To change water by one degree takes 80 calorie per gram. This means that the water releases 2800 calories when it shifts from 100 to 99 degrees Celsius.

Answer 4

Q = mc(delta)T

Q = 50 x 1 x (100-37)

Q = 3150 calories

Answer 5

3150 calories 3.15 kcal
