8. Exactly 169.5 J will raise the temperature of 10.0 g of a metal from 25.0°C to 60.0°C. What is the specific heat capacity of the metal?

THE SPECIFIC HEAT OF THE METAL IS 0.4843 J/G °C

Explanation:

Heat involved in the reaction is 169.5 J

mass of the metal = 10 g

Change in temperature = 60 °C - 25 °C = 35 °C

Specific heat of the metal = unknown

Specific heat of a metal or substance is the amount of heat per unit mass required to raise the temperature by one degree Celsius.

Using the formula for heat of a reaction, which is:

Heat = mass * specific heat * change in temperature

Heat = m C ΔT

Re-arranging the formula by making C the subject of the formula, we get:

C = Heat / m ΔT

C = 169.5 J / 10 g * 35 C

C = 169.5 J / 350 g °C

C = 0.4843 J/g°C

So therefore, the specific heat of the metal is 0.4843 J/ g°C

the correct answer is:
