Thermal energy is caused by motion of?
1. mixing water molecules contained in a beaker
2. molecules in soild liquid and gas phases
3. mixing molecules together
4. molecules that have reached equilibrium
the density of an object with the volume of 60.0 mL and a mass f 400.0 g is
1. 0.150 g/ml
2. 2.89 g/mL
3. 5.50 g/mL
4. 6.67
Ms. Sue may just be tired of us giving the answers to people who desperately need them to pass what a shame 😂
so then would it be 3. mixing molecules together?
Thankz J-man.
No I got 4 out of 35
Ya'll gotta realize, some teachers make it so the questions are put about randomly, and you can have a similar question, but different answer options. So @:) would have had to give you the answer along with each question because some people have different questions, the questions could be in a different order, and you could also end up with different options for your answers.
density=mass/volume=400/60=?
Thermal energy is molecules in motion. The more the motion, the highter the temperature (and energy).
Temperature is a measure of the average kinetic energy of molecules.
everyone report sue she isn’t a great role model
answers to entire test please
1. gas
2. solid liquid gas
3. 6.67
4. aluminmum
5. the glass has lower heat in a swimming pool
6. chemical change
7. liquid, loses energy
8. vibrating more slowly in that area
9. equal to the mass before and after
10. different states of matter
11. different chemical and physical properties
12. apperince
13. collum a is physical and b is chemical
The rest is being graded.
promise 13 of 13 i did the test got a 11/ 13 but i can review my answers and these are the right ones your welcome!
