The Gibb's free energy equation for a system undergoing phase transition is given by ΔG = ΔH - TΔS, where ΔG is the change in Gibb's free energy, ΔH is the change in enthalpy, ΔS is the change in entropy and T is the temperature in Kelvin.
During melting transition, two systems A and B, show no difference in ΔH but B exhibits 10% lower ΔS than A. The ratio of melting temperature of B to that of A (rounded off to 2 decimal places) is

A building has several rooms and doors as shown in the top view of the building given below. The doors are closed initially. What is the minimum number of doors that need to be opened in order to go from the point P to the point Q?
Ques 39 GATE 2022
A game consists of spinning an arrow around a stationary disk as shown below. When the arrow comes to rest, there are eight equally likely outcomes. It could come to rest in any one of the sectors numbered 1, 2, 3, 4, 5, 6, 7 or 8 as shown. Two such disks are used in a game where their arrows are independently spun. What is the probability that the sum of the numbers on the resulting sectors upon spinning the two disks is equal to 8 after the arrows come to rest?
