Question

How many Joules of energy are needed to raise 87.3 grams of aluminum from 22,5 C to 47.3. C. The specific heat of aluminum is 0.903 V&C.

Joules

Answer 1

Energy needed : 1955.03 J

Further explanation

Heat can be formulated:

Q=m.c.Δt

Q=heat,J

m=mass,g

c=specific heat,J/g °C

Δt=temperature, °C

m=87.3 g

Δt= 47.3-22.5=24.8 °C

c=0.903 J/g °C

`\tt Q=87.3* 0.903* 24.8=1955.03~J`
