The specific Heat of gold is 0.128 J/g degrees Celsius. How much heat would be needed to warm 250.0g of gold from 25.0 degrees Celsius to 100.0 degrees Celsius

2400

2.40 x 10^3 J

To calculate the amount of heat needed to warm a substance, we can use the formula:

Q = m * C * ΔT

Where:
Q = amount of heat (in joules)
m = mass of the substance (in grams)
C = specific heat capacity (in J/g°C)
ΔT = change in temperature (in °C)

In this case, we are given:
m = 250.0 g (mass of gold)
C = 0.128 J/g°C (specific heat of gold)
ΔT = (100.0°C - 25.0°C) = 75.0°C (change in temperature)

Now, we can plug in the values into the formula:

Q = 250.0 g * 0.128 J/g°C * 75.0°C

First, multiply the mass (250.0 g) by the specific heat (0.128 J/g°C):
Q = 32.0 J/°C * 75.0°C

Next, multiply the result by the change in temperature (75.0°C):
Q = 2,400 J

Therefore, the amount of heat required to warm 250.0 g of gold from 25.0°C to 100.0°C is 2,400 joules.
