When might it be important to know the flow rate of a gas?
You could have job that requires its flow rate to be measured precisely. For example, if you work as a scientist and you are doing an experiment, it's important that you know the flow rate of the gas.
Where can flow rate be observed in real life?
at a gas station
If air is blown through the larger end of a cone how do you calculate what the pressure of the air exiting the smaller end will be?
You'll use these two equations: Ideal Gas Law: P=pRT (where P=pressure, p=density, R=gas constant, T=temperature) and also conservation of mass/energy principle: sum of mass flow rate in=sum of mass flow rate out and since m=pvA (where m=mass flow rate, p=density, v=velocity, and A=cross-sectional area) you can write pvA(in)=pvA(out) Using these 2 equations you should be able to solve the problem.
What effect does raising the temperature of a gas have on its pressure if the volume of the gas and the number of particles are kept constant?
As per Charles' law pressure increases as temperature increases provided volume is kept constant
What is the effect of varying the temperature on the volume of a constant mass of a gas at a constant pressure?
the relation is given by charles law which says that the volume of a constant mass of gas at constant pressure is directly proportional to the temperature so increase in temperature causes an increASE in the volume
What is the effect of the temperature on the gas flow?
higher temperature equals more flow, which reduces mpg.
What is the effect of flow rate on retention time in HPLC?
When you increase the flowrate of the carrier gas, the retention times decrease. Just like when you increase the temperature of the column. Both of these conditions are sometimes necessary for substances that would otherwise have very long retention times.

What is one relationship between temperature and rate of gas production in yeast?
There is a direct proportional relationship between temperature and rate of gas production in yeast. The higher the temperature the more gas will be produced.
Where can flow rate be observed in real life?
at a gas station
What are 3 measurements when working with a gas?
Pressure,Temperature and Flow
What happens to the rate of dissolution as the temperature is increased in a gas solution?
The rate decreases.
What happen to the rate of dissolution as the temperature is increased in a gas solution?
The rate decreases.
How might speed at which a gas particle moves affects how quickly that gas particle escapes from the balloon?
Flow rate is diameter of hole*velocity, so the higher the velocity the higher the flow rate.
Does heating compressed air make it move quicker?
If you heat compressed air but keep it at the same pressure, it will expand, becoming less dense. If you want to keep the mass flow rate the same, the volumetric flow rate, and hence the linear velocity, must increase. At the same time, increasing the temperature of a gas actually increases it's viscosity. so for a given pressure drop, your mass flow rate will decrease and effectively the gas will move slower.
When a gas is allow to expand what will its effect on temperature?
It cools.
What are flow meters used for?
Flow meters are used to measure the linear, nonlinear, mass, or volumetric flow rate of a liquid or gas.
