# Water Temperature Calculations

Water at 50 degrees C can be obtained by mixing together which one or more of the following combinations? Which of the others would have final temperatures higher than 50 degrees C and which lower than 50 degrees C? What will be the final temperatures for these combinations?

a. 1 kilogram of ice at 0 degrees C and 1 kilogram of steam at 100

degrees C.

b. 1 kilogram of ice at 0 degrees C and 1 kilogram of water at 100

degrees C.

c. 1 kilogram of water at 0 degrees C and 1 kilogram of steam at 100

degrees C.

d. 1 kilogram of water at 0 degrees C and 1 kilogram of water at 100

degrees C.

#### Solution Preview

Answer:

The latent heat of evaporation at 100C is 540 cal/g

The latent heat of melting at 0C is 80 cal/g

Therefore:

a.

Every gram of ice will take (80 + 100) cal to melt and warm up to 100C.

It would take only (180/540) = (1/3) kg of the ...
