Measuring Heat Capacity Flashcards
What is the formula for energy transferred?
Energy transferred = mass x specific heat capacity x temperature change
What units should mass have in the energy transferred formula?
Mass should be in kg
What are the units for specific heat capacity?
J/kg C
What is the formula for power?
Power (watts) = energy transferred (joules) / time (seconds)
What is the unit of power?
Watts
Formula for energy transferred?
Energy transferred =. power x time
How do we graphically determine the specific heat capacity?
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
