1. What are the standard Kilograms, metres and seconds
units of mass, length
and time?
2. What are the SI prefixes kilo, mega, giga
for 10^3, 10^6 and 10^9?
3. What are the SI prefix- milli, micro, nano
es for 10^-3, 10^-6 and
10^-9?
4. What is work done? The energy transferred in moving something
5. What is power? the rate at which work is done
6. What happens to a gas Particles get closer together
when it is compressed? Gas pressure increases
More collisions between particles and container
Temperature of gas rises
7. How do you calculate The area under the graph
work done from a P-V
graph?
8. What is efficiency? the percentage of the work input that becomes
useful work output
9. What is thermal equilib- when two objects have the same temperatures
rium? and net heat transfer is zero
10. What is the first law of The change in a system's internal energy is equal
thermodynamics? to the difference between heat added to the sys-
tem from its surroundings and work done by the
system on its surroundings
11. What are ideal gases? All collisions are elastic
All motion is random
There are no forces between particles
12. What is absolute zero?
