Identify why a balloon was stretched over the top of the conical flask.It has no purposeTo show how heat affects the particles of rubber in the balloonTo help show that a gas is formedTo help show that a liquid is formed

What happens to the pressure inside a balloon when someone squeezes it (i.e., decreases its volume)? Explain what is happening to the gas particles.Answer text Question 2Rich text editor

Hold the bottle and pull down on the knot of the balloon at the bottom. Describe what happens to the balloon inside the bottle.

(d)     The air in the balloon had a mass of 0.00320 kgThe temperature of the air in the balloon decreased by 215 °CThe change in thermal energy of the air in the balloon was 860 JCalculate the specific heat capacity of the air in the balloon.

Determine why gases rise when they are heated. The particles lose kinetic energy and move closer togetherThe particles gain kinetic energy and move further apartSome of the particles are destroyed so the gas gets lighterThe particles get smaller and lose weight

What effect will the heat have on the air inside the bottle/balloon?*1 pointThermal contraction.Temperature decrease.Thermal expansion.Change in state.
