consider the following scenario:
our sample starts at room temperature (300 k). we place our sample in the oven set to 500k. we then let our sample cool back to room temperature. what is our δt?

Explanation:

Question 5

Pressure in gases is defined by the collisions of gas particles with the container walls, including the frequency (number) of collisions and the energy of those collisions. Temperature relates to average kinetic energy of particles, volume is the space occupied, and moles are the amount of substance—none match the description as pressure does.

By definition, state functions depend only on the initial and final states, not the path taken to reach the final state (e.g., internal energy, enthalpy, pressure, temperature, volume are state functions; work and heat are not as they depend on path). So the statement is true.

Step1: Recall the formula for temperature change

The formula for temperature change is $\Delta T = T_{final} - T_{initial}$.

Step2: Identify initial and final temperatures

The initial temperature $T_{initial}$ is 300 K. After heating and cooling, the final temperature $T_{final}$ is also 300 K (back to room temperature).

Step3: Calculate $\Delta T$

Substitute into the formula: $\Delta T = 300\ \text{K} - 300\ \text{K} = 0\ \text{K}$.

Answer:

A. Pressure
