Getting down to eye level to read the thermometer reduces which type of error?
Human error
Random error
Systematic error
Not having the thermometer fully in the water increases which type of error?
Human error
Random error
Systematic error
What is the function of the heat proof mat and lid?
To reduce heat energy loss
To reduce dissipation of heat to the surroundings
To reduce the amount of energy wasted
All of the above
Which type of material would we expect to be the best insulator?
Tin foil, it is a metal so keeps the heat in
Paper, it doesn't absorb the heat energy very well
Wool, it has a lot of air pockets to trap the heat
Why do we use a digital stop clock to measure time?
To reduce random error
To increase repeatability
To reduce direct proportion
The digital stop clock measures to 1/100th of a second, a regular clock can only measure to the nearest 1 second. Which feature is better on the stop clock?
Repeatability
Resolution
Dissipation
Insulation
The digital stop clock measures to 1/100th of a second, a regular clock can only measure to the nearest 1 second. Does the stop clock have a higher or lower resolution?
Higher
Lower
Adding more layers of material to the beaker reduces which feature?
Thermal energy
Thermal insulation
Thermal conductivity
Thermal temperature
Give one safety precaution you should take when carrying out the insulation required practical.
