give the specific heat for aluminum is 0.900 J/g*c how much energy is required to raise 25.0 g of aluminum from 20.0 to 75.0
q = mass Al x specific heat Al x (Tfinal-Tinitial)
To find the amount of energy required to raise the temperature of aluminum from 20.0 °C to 75.0 °C, you can use the specific heat formula:
q = m * c * ΔT
Where:
q is the amount of energy (in Joules)
m is the mass of the substance (in grams)
c is the specific heat (in J/g·°C)
ΔT is the change in temperature (in °C)
Given:
m = 25.0 g
c = 0.900 J/g·°C
ΔT = (75.0 °C - 20.0 °C) = 55.0 °C
Now, plug these values into the formula:
q = 25.0 g * 0.900 J/g·°C * 55.0 °C
Calculating:
q = 1237.5 J
Therefore, it would require 1237.5 Joules of energy to raise 25.0 grams of aluminum from 20.0 °C to 75.0 °C.
To calculate the energy required to raise the temperature of a substance, you can use the formula:
Q = m * c * ΔT
Where:
Q is the energy required
m is the mass of the substance
c is the specific heat of the substance
ΔT is the change in temperature
In this case, you have:
m = 25.0 g (mass of aluminum)
c = 0.900 J/g°C (specific heat of aluminum)
ΔT = 75.0°C - 20.0°C = 55.0°C
Now, substitute these values into the formula to calculate the energy required:
Q = 25.0 g * 0.900 J/g°C * 55.0°C
To get the final answer, simply multiply the values:
Q = 1237.5 J
Therefore, the energy required to raise 25.0 g of aluminum from 20.0°C to 75.0°C is 1237.5 Joules (J).
