If hydrogen temperature goes from 50 tp 75 degrees Celsius in 22g sample, how much heat was used? Give explanation!

A. 15,730 J

B. 23,595 J

C. 7865 J

D. 550 J

The heat used if the hydrogen temperature goes from 50 to 75 c is calculated using

Q (heat) = M (mass) xC (specific heat capacity for hydrogen) x deltaT (change in temperature) formula

Q=?

m = 22g

c = 14.3 j/g/c

delta T = 75-50 = 25c

Q = 22 g x 14.3 j/g/c x 25 = 7865 j (answer c)
