You can Find the Specific Heat Capacity of Water Flashcards
If you can, what should you use for both of these experiments to reduce energy wasted to the surroundings?
A thermally insulated container
What do you do first?
Use a mass balance to measure the mass of the insulating container
What do you do second?
Fill the container with water and measure the mass again
What is the difference in mass?
The mass of the water in the container
What do you do third?
Set up experiment (see page 57) and make sure the joulemeter reads 0 and place a lid on the container if you have one
What do you do fourth?
Measure the temp of the water, then turn on the power
What do you do fifth?
Keep an eye on the thermometer
What do you do when the temperature has increased?
Switch off the power and record this temp increase and the energy on the joulemeter
What do you then calculate?
The specific heat capacity of the water by rearranging the equation and plugging in your measurements
What do you do last?
Repeat the whole experiment at least 3 times, then calculate an average for the specific heat capacity
SHC of a solid - what do you make sure the block of material you use has?
Two holes in it for the heater and the thermometer, and wrap it up with an insulating layer before starting
SHC of a solid - What do you do when you have switched off the power and finished timing?
Wait until the temp has stopped increasing before recording the highest final temp - gives energy from heater time to spread through solid block
