Internal energy in a system
U = Ek + Ep
a body in uniform circular motion has a constant...... and a change in the ....... hence it has velocity
constant speed and direction
The advantage of this thermometer is that it can measure from -100 C to 1500C

Give a disadvantage of the mercury in glass thermometer
It is expensive, it can't measure temperatures below -40 C and it's poisonous.
uses the pressure change with the temperature of a gas at constant volume.
