Question 4 (0.5 points) The gas equation for one mole of oxygen related its pressure P (in atmospheres), its temperature, T (in Kelvin, K) and its volume V (in cubic decimeters, (11113] is given below 16 1 2 T: P I 12PV V 2V2 5 Suppose at time t, the volume is 5 dmg, and the pressure is 2 atm. (a) Find the temperature T at this moment. Enter your answer in the blank below. (b) Find the rate of change of the pressure if the temperature remains constant and the volume is increasing at a rate of 0.1 dm3fmin. (c) Is the pressure increasing or decreasing in time
