Question:
The specific heat of a substance is 0.38 J/goC. How much energy is required to raise the temperature of 42 g of the substance from 25oC to 39oC?
Answers
Answer:223.4JExplanation:Given parameters: Specific heat capacity of substance = 0.38J/g°C Mass of substance = 42g Initial temperature = 25°CFinal temperature = 39°C Unknown: Energy required to raise the temperature = ? Solution: The amount of heat required by the substances can be derived using the expression below; H = m c Δt H is the amount of heat energy m is the mass c is the specific heat capacity Δt is the change in temperature; Δt = 39°C - 25°C = 14°C Now insert the parameters and solve; H = 42 x 0.38 x 14 = 223.4J
