**Answer is:**

### 2 and 3

**Explanation:**

In thermodynamics

Work is path dependent function

Work is area under the curve in a PV diagram

**Answer is:**

### 2 and 3

**Explanation:**

Heat and Work are not completely interchangeable forms of energy

Work can be converted completely into heat

**Answer is:**

### (3/4)

**Explanation:**

Total outcomes={HH,HT,TH,TT}=4

Favorable outcomes(at least one head)={HT,TH,HH}=3

Probability of getting at least one head = favorable outcomes/total outcomes = 3/4

Hence Probability of getting at least one head is 3/4
