Answer:

1. The gas law used: Dalton's law of partial pressure.

2. Pressure of nitrogen = 331 mmHg

Explanation:

From the question given above, the following data were obtained:

Total pressure (Pₜ) = 592 mmHg

Pressure of Oxygen (Pₒ) = 261 mmHg

Pressure of nitrogen (Pₙ) =?

The pressure of nitrogen in the sample can be obtained by using the Dalton's law of partial pressure. This is illustrated below:

Pₜ = Pₒ + Pₙ

592 = 261 + Pₙ

Collect like terms

592 – 261 = Pₙ

331 = Pₙ

Pₙ = 331 mmHg

Therefore, the pressure of nitrogen in the sample is 331 mmHg

JulijaS [17]

The heat change is related to specific heat as

Heat change = mass of substance X specific heat X change in temperature

So if we are considering same amount of substance

and we are starting with the same temperature

the change in temperature will be inversely proportional to the specific heat

higher the specific heat lower the temperature change

Thus the change in temperature will be least for the substance with highest specific heat.
