I just wanted to give answers For the quick check of kinetic and thermal energy
1. What is kinetic energy?
the energy of movement
2. A fisherman in a boat drinks a hot cup of coffee. The big lake under his boat is full of cold water. Which statement is an accurate comparison of lake water and coffee?
The coffee will have more total heat energy and the coffee particles will move faster.
3. The gallium in the image melts in the person’s hand. What changes will occur at the microscopic level?
Gallium atoms will gain potential energy, moving freely from each other.
4. Which object will have particles with the highest average kinetic energy?
a drop of water at 90°C
5. Thermal energy is transferred to a substance. What change can happen?
Particles can gain potential and kinetic energy.
These are the answer, I promise they are 100%, I did it in LL with a teacher 🙂
Hail Hydra > 🙂 Just wanted to give answers
For the quick kinetic and thermal energy check I got #2 wrong, they are correct and have a nice lifespan
1. What is kinetic energy?
the energy of movement
2. A fisherman in a boat drinks a hot cup of coffee. The big lake under his boat is full of cold water. Which statement is an accurate comparison of lake water and coffee?
The LAC will have more total heat energy and the coffee particles will move faster.
3. The gallium in the image melts in the person’s hand. What changes will occur at the microscopic level?
Gallium atoms will gain potential energy, moving freely from each other.
4. Which object will have particles with the highest average kinetic energy?
a drop of water at 90°C
5. Thermal energy is transferred to a substance. What change can happen?
Particles can gain potential and kinetic energy. number 2
The lake will have more total heat energy, but the coffee particles will move faster.
sorry this is actually the correct answer for #2 my wrong i put the wrong hail hydrdra is right!!!! tysm hydra is wrong i was all wrong the answers are
D. energy of motion
D. The lake will have more total heat energy, but the coffee particles will move faster.
B. Gallium atoms will gain potential energy, moving freely from each other.
C. a drop of water at 90°C
C. Particles can gain potential and kinetic energy. i got 100 on my tysm test hail hydra you just made my day hail hydra is right thanks :0 Thanks Hydra i messed up number 2 because you put the wrong answer i used jiskha on all my quick checks today and i got a lot of 100% so 1 question wrong won’t be bad thanks for the answers you got i got them all wrong cool beeevee is correct except number 2 is wrong the answer was actually BUT not AND #2 is that the lake will have more total heat energy but the coffee particles would move faster @sunflower is 100% @Hail Hydra, @sunflower, @Not Kool-aid Gurl, @BeeVee and @htsrhtdyjy are all confirmed to be correct. TYSM guys, you really helped everyone and I appreciate you all. 🙏
BTW I called Captain America and he’s coming back for the Hydra cult LOL D
