Answer to Question #151461 in General Chemistry for hannia

Question

How much heat is required to raise the temperature of 20 grams of titanium from 13 degrees
C to 25 degrees C?

Answer 1

We know the formula,

Absorbed heat, H = M S (T2–T1)

Mass, M = 20g

Specific heat, S = 0.72 J/(g°C)

Initial temperature,T1 = 13°C

Final temperature,T2 = 25°C

So, H = 20×0.72×(25–13)

= 172.8 J

Hence, 172.8 J heat is required
