True
Explanation:
Average speed is a scalar magnitude as opposed to average velocity which is a vector. The unit of measurement in the International System (S.I.) of the average speed is the meter per second (m/s).
Answer:
a
The pressure will increase
b
Explanation:
From the ideal gas law we have that
We see that the temperature varies directly with the pressure so if there is an increase in temperature that pressure will increase
The initial temperature is 
The objective of this solution is to obtain the temperature of the gas where the pressure is tripled
Now from the above equation given that nR and V are constant we have that
=> 
Let assume the initial pressure is 
So tripling it will result to the pressure being 
So
=> 
=>
=> 
Converting back to 
=>
Distillation
Explanation:
The name of the process used to refine oil into different products is called distillation. A refinery has huge distillation columns where is separated into its different fractions.
- Distillation is a separation technique in which a mixture such as crude oil is separated into its fractions.
- The components of the mixture must have an appreciable boiling point difference.
- After distillation, oil is separated into difference components such as heavy oil, natural gas, kerosene, gasoline e.t.c.
- The liquid with the least boiling point rises up in the column first and is collected.

Answer:
As r decreases, we lose gravitational potential energy - in other words, U G U_G UGU, start subscript, G, end subscript becomes more negative. Because energy is conserved, the velocity must increase, resulting in an increase in kinetic energy.
