Question

11. What information is missing from the following question? "A small ball is inflated to 100 kPa of pressure. What is the final pressure if the temperature increases by 20°C? "

Answer 1

The initial temperature

Step-by-step explanation:

Ideal gas laws help us understand how the properties of a gas can change.

Gay-Lussac's Laws

One of the ideal gas laws is Gay-Lussac's law. This law relates pressure to temperature. The law states that pressure and temperature have a direct relationship. This means that as one increases, so will the other. The equation for Gay-Lussac's law is:

• 
  `\displaystyle (P_1)/(T_1) =(P_(2) )/(T_2)`

Missing Information

If we look at the equation, there are 4 possible pieces of information to plug in: the initial pressure, initial temperature, final pressure, and final temperature. We are told that we are solving for the final pressure, so we will need the other three pieces of information. However, we are only given the change in temperature. Since we do not know the initial temperature, we cannot find the final temperature or solve the equation.
