What is the specific heat of Gold if 15.3 J of heat changes 12 grams by 8 degrees Celsius? I got 7.834, would this be correct do you think? Thanks Jiskha.
To calculate the specific heat of gold, you need to use the formula:
q = m * c * ΔT
where:
q is the amount of heat transferred (in joules),
m is the mass of the substance (in grams),
c is the specific heat capacity of the substance (in J/g°C), and
ΔT is the change in temperature (in °C).
In this case, you know the following values:
q = 15.3 J
m = 12 g
ΔT = 8°C
Rearranging the equation, we have:
c = q / (m * ΔT)
c = 15.3 J / (12 g * 8°C)
c = 15.3 J / 96 g°C
c ≈ 0.159 J/g°C
So, the specific heat of gold would be approximately 0.159 J/g°C, not 7.834 as you mentioned.
To avoid calculation errors, always double-check your work by performing the calculations step by step.
