Answer:
First you need to know that the warm air is less dense than the colder air and thus it tends to rise; so snow-caves are constructed in some way that the tunnel entrance is below the main space, and so the warm air can be retained into the cave. In a typical snow-cave, you can reach temperatures over 0°C even when the temperature outside are under zero degrees celsius.

Answer:
Explanation:
From the information above:
The equation for the reactor volume of CSTR is given by the formula:
The reaction rate of A is:
and k = 3 dm³/mol.h
replacing the values in the above equation to solve for v;
∴
V = 66,000 dm³
Thus, the reactor volume of CSTR is 66000 dm³
Taking the differential mole balance equation for PFR is as follows:
Taking the integral between initial and final concentrations;
replace the values in the above equation;
Thus, the reactor volume of PFR is 660 dm³
