a)A cyclinder of gas....which statement about pressure is true
b) A cyclinder of gas....which statement about temperature is true
A cylinder of gas has a tightly fitting piston. If the piston is pushed in. i. the pressure of the gas
increases. ii. the pressure of the gas decreases ii the pressure of the gas remains the same iv, we
can't predict whether the pressure will increase, decrease, or remain the same. Which of these
statements is true? Why? A cylinder of gas has a tightly fitting piston. If the piston is pushed in,
i. the temperature of the gas increases. i. the temperature of the gas decreases. ii. the temperature
of the gas remains the same. v. we can't predict whether the temperature will increase, decrease,
or gemain the same. Which of these statements is true? Why?
Solution
a] pressure will increase because it is inversely proportional to temperature.
b] temperature will remain same, because it can deacrease only if pressure is kept same and
volume decreases which doesnt happen when piston is pushed in.
