what is the specific heat of aluminum if the temperature of a 28.4 g sample of aluminum is increased by 8.1 C when 207 J of heat is added?

Answer: 0.9J/g°C.

Explanation:

Specific heat of Aluminum is the amount of heat required to raise one gram of Aluminum by one degree Celsius.

The formular is Q=mc∆T

Where Q is energy in joules.

M is mass in gram.

C is specific heat.

∆T is change in temeprature in degree Celsius.

Mass=28.4g

C=?

T=8.1°c

Q=207j.

Q=MC∆T

207= 28.4× C× 8.1

207=230.04C

C=207÷230.04

C=0.9J/g°C.

The specific heat of aluminum is 0.9 J/g°C.

What is specific heat?

The specific heat capacity of any substance is the heat capacity divided by the mass of the substance.

By the formula

Q=mc∆T

Q is the energy which is 207 J

m is mass, which is 28.4 g

T is temperature which is 8.1 C

delta is change in temperature

Putting the values in the formula

Q=mc∆T

207 = 28.4 × c × 8.1

c = 0.9 g/J

Thus, the specific heat capacity of aluminum is 0.9 g/J
