Calculate the heat energy needed to change the temperature of 2 kg of copper from 10°C to 110°C.

I forgot the formula

heat in = mass * specific heat of copper * temperature rise

assuming it does not change state and copper does not melt at that temp.

Heat in= (2kg)(.34)(100)

The formula to calculate the heat energy needed to change the temperature of a substance is:

Q = mcΔT

Where:
Q = heat energy (in joules)
m = mass of the substance (in kilograms)
c = specific heat capacity of the substance (in joules per kilogram per degree Celsius)
ΔT = change in temperature (in degrees Celsius)

For copper, the specific heat capacity is approximately 390 J/kg°C.

Using the given values:
m = 2 kg
ΔT = 110°C - 10°C = 100°C
c = 390 J/kg°C

Now, we can substitute the values into the formula and calculate the heat energy (Q):

Q = (2 kg) * (390 J/kg°C) * (100°C)
Q = 78,000 J

Therefore, the heat energy needed to change the temperature of 2 kg of copper from 10°C to 110°C is 78,000 joules.

To calculate the heat energy needed to change the temperature of a substance, you can use the formula:

Q = m * c * ΔT

Where:
Q = Heat energy (in joules)
m = Mass of the substance (in kilograms)
c = Specific heat capacity of the substance (in joules per kilogram per degree Celsius)
ΔT = Change in temperature (in degrees Celsius)

For copper, the specific heat capacity is approximately 385 J/kg°C.

Given:
m = 2 kg
c = 385 J/kg°C
ΔT = 110°C - 10°C = 100°C

Plugging in the values into the formula:

Q = 2 kg * 385 J/kg°C * 100°C
Q = 77,000 J

Therefore, the heat energy needed to change the temperature of 2 kg of copper from 10°C to 110°C is 77,000 joules.
