Inertia is the retaliation of an object to change in its velocity
Answer:

Explanation:
First of all we need to calculate the heat that the water in the cooler is able to release:

Where:
- Cp is the mass heat capacity of water
- V is the volume
is the density


To calculate the mass of CO2 that sublimes:

Knowing that the enthalpy of sublimation for the CO2 is: 


(P1V1/T1)=(P2V2/T2)
I just took the test and this should be correct
Answer: it is 5.5 mg
Explanation:
you have to multiply the mass value by 1000
