How much energy is required to increase the temperature of an object with a mass of 1.5 g from 24 °C to 90 °C if its specific heat capacity is 4.2 J/(°C·g)?
1 Answer
You calculate the amount of energy required by using the specific heat capacity formula.
Explanation:
All we are doing is using the formula for specific heat capacity:
=>
=>
=>
=>
Now we just sub in the variables accordingly.
#q=mcDeltaT#
#=(1.5)(4.2)(90-24)#
#=415.8#
Therefore, the substance requires
