Question

1. the temperature of a gas is directly related to the kinetic energy of the gas particles. determine which actions below will have no effect on the kinetic energy of gas particles.

i. poking a hole in a tire
ii. sticking an inflated balloon in a freezer
iii. adding more air to a balloon
iv. lighting a candle
v. setting a block of ice on the dining room table
a iv and v
b i and iii
c i, iii, and v
d ii, iii, and iv

Explanation:

To determine which actions affect gas particle kinetic energy (related to temperature), analyze each:

• I. Poking a tire hole: Changes volume/pressure, not temperature (kinetic energy depends on temp, so no effect).
• II. Freezer balloon: Lowers temp, reduces KE (has effect).
• III. Adding air to balloon: Changes amount of gas, not temp (no effect on KE of existing particles).
• IV. Lighting candle: Increases temp, increases KE (has effect).
• V. Ice on table: Ice melts (solid/liquid), no direct effect on gas particle KE (temp of gas in room likely stable).

So I, III, and V have no effect on gas particle KE.

Answer:

C. I, III, and V
