The question I need help with is in the photo

Answer 1

Answer: 144.2

Step-by-step explanation:

Note that
`23.0^(\circ)\text{C}=298.0\text{ K}`.

Using the formula
`(V_1)/(T_1)=(V_2)/(T_2)` yields:

`(2.45)/(T_1)=(1.75)/(298)\\\\T_1=(298 * 2.45)/(1.75) \text{ K}\\\\T_1=(298 * 2.45)/(1.75)-273^(\circ)\text{C}\\\\T_1=144.2^(\circ)\text{C}`
