calculate the heat energy required to raise the temperature of a 500. gram iron pipe from 25 degress celcius to 100 degrees celcius. the specific heat for iron is .45 J/g degrees celcius
Note the correct spelling of celsius.
q = mass Fe x specific heat Fe x delta T.
12.38j
To calculate the heat energy required to raise the temperature of an object, you can use the formula:
Q = m * c * ΔT
where:
Q is the heat energy
m is the mass of the object
c is the specific heat capacity of the material
ΔT is the change in temperature
In this case, the mass of the iron pipe is given as 500 grams, the specific heat capacity of iron is 0.45 J/g°C, and the change in temperature is from 25°C to 100°C.
Let's substitute these values into the formula:
Q = 500 g * 0.45 J/g°C * (100°C - 25°C)
First, subtract the temperatures: 100°C - 25°C = 75°C
Then, multiply the mass, specific heat capacity, and change in temperature:
Q = 500 g * 0.45 J/g°C * 75°C
Q = 16875 J
Therefore, you would need 16875 Joules of heat energy to raise the temperature of a 500 gram iron pipe from 25°C to 100°C.
