Answer:

690j

Explanation:

Use the formula

q

=

m

C

Δ

T

q = heat absorbed or released, in joules (J)

m = mass

C = specific heat capacity

ΔT = change in temperature

Plug known values into the formula.

q

=

50

(

.92

)

(

15

)

q

=

690

therefore, 690 joules of heat energy are needed.
