Measuring Heat Capacity Flashcards
1
Q
What is the formula for energy transferred?
A
Energy transferred = mass x specific heat capacity x temperature change
2
Q
What units should mass have in the energy transferred formula?
A
Mass should be in kg
3
Q
What are the units for specific heat capacity?
A
J/kg C
4
Q
What is the formula for power?
A
Power (watts) = energy transferred (joules) / time (seconds)
5
Q
What is the unit of power?
A
Watts
6
Q
Formula for energy transferred?
A
Energy transferred =. power x time
7
Q
How do we graphically determine the specific heat capacity?
A
Plot a graph of temperature against energy transferred
Energy transferred on x axis and temperature on y axis
Draw a line of best fit
Calculate the gradient of the line of best fit
Specific heat capacity = 1 / gradient
