Question

How much heat is required to raise the temperature of a 55 g glass ball by 16°C?

Answer 1

To calculate the heat required to raise the temperature of a substance, use the formula q = mcΔT, where q is the amount of heat transferred, m is the mass of the substance, c is the specific heat of the substance, and ΔT is the change in temperature.

Step-by-step explanation:

To calculate the amount of heat required to raise the temperature of a substance, we use the formula:

q = mcΔT

Where:

q is the amount of heat transferred

m is the mass of the substance

c is the specific heat of the substance

ΔT is the change in temperature

In this case, we know the mass of the glass ball is 55 g and the change in temperature is 16°C. We need the specific heat of glass to complete the calculation. Once we have that, we can plug in the values and calculate the heat required.

Answer 2

When an object gets heated by a temperature ΔT energy needed, E = mcΔT

Here mass of glass = 55 g =
`55*10^(-3)kg`

Change in temperature ΔT = 16^0C[/tex] = 16 K

Specific heat of glass = 0.84 J/gK = 840 J/kgK

Substituting we will get

E =
`55*10^(-3)`*840*16 = 739.2 J

So a heat of 739.2 J is required to raise the temperature of a 55 g glass ball by 16°C
