(58) the pressure of a gas in a tank is 422 psi at
20.0k. what is the pressure at 60.0k?
a. 1270 psi
7.480 atm
c. 1270 atm
d. 480 psi

1270 Psi

We are given;

We are required to determine the pressure at 60.0 K

Hence;

Therefore;

P₂=1266 Psi

   = 1270 Psi

Thus, the pressure at 60.0 K is 1270 Psi

radioactive decay occurs in unstable atomic nuclei – that is, ones that don't have enough binding energy to hold

the nucleus together due to an excess of either protons or neutrons.

i just learnt this recently but i need to look through my notes again
