What amount of heat is required to increase the temperature of 75.0 grams of gold from 150°C to 250°C? The specific heat of gold is 0.13 J/g°C.
Q = M*C*(delta T)
Do the multiplication. Q is the heat required. C is the specific heat.
To calculate the amount of heat required to increase the temperature of a substance, you can use the formula:
Q = m × c × ΔT
where Q is the amount of heat, m is the mass of the substance, c is the specific heat, and ΔT is the change in temperature.
In this case, the mass of gold (m) is given as 75.0 grams, the specific heat of gold (c) is 0.13 J/g°C, and the change in temperature (ΔT) is 250°C - 150°C = 100°C.
Now, substitute these values into the formula to find the amount of heat (Q):
Q = 75.0 grams × 0.13 J/g°C × 100°C
First, multiply the mass (m) by the specific heat (c):
Q = 9.75 J/°C × 100°C
Q = 975 J
Therefore, it would require 975 Joules of heat to increase the temperature of 75.0 grams of gold from 150°C to 250°C.
