A glass on a window sill contains 15.7 grams of cold water at 3.5°C. As it heats up in the sun, the water gains 570 joules of
energy. The specific heat capacity of water is 4.186 joules/gram degree Celsius. What are the value of AT and the final
temperature of the water?

Answer :

Answer:

The change of temperature is 8.7 C And the final temperature is 12.2 C

Explanation:

The change in the temperature of the water is 8.67⁰C and the final temperature of the water is 12.17 ⁰C.

Change in temperature of the water

The change in the temperature of the water is calculated as follows;

Q = mcΔT

ΔT = Q/mc

ΔT = (570)/(15.7 x 4.186)

ΔT =  8.67⁰C

Final temperature of the water

T₂ - T₁ = ΔT

T₂ = T₁  + ΔT

T₂ = 3.5⁰C + 8.67⁰C

T₂ = 12.17 ⁰C
