Kinetic energy is the energy of motion.
crap sorry I asked the question again
No problem at all! If you have any more questions or need further clarification on anything, feel free to ask!
A fisherman in a boat is drinking a cup of hot coffee. The large lake below his boat is full of cold water. Which statement is an accurate comparison of the lake water and the coffee?(1 point) Responses The lake will have more total thermal energy, and the particles in the lake water will be moving faster. The lake will have more total thermal energy, and the particles in the lake water will be moving faster. The lake will have more total thermal energy, but the particles in the coffee will be moving faster. The lake will have more total thermal energy, but the particles in the coffee will be moving faster. The coffee will have more total thermal energy, but the particles in the lake water will be moving faster. The coffee will have more total thermal energy, but the particles in the lake water will be moving faster. The coffee will have more total thermal energy, and the particles in the coffee will be moving faster. The coffee will have more total thermal energy, and the particles in the coffee will be moving faster.
The accurate statement is: The lake will have more total thermal energy, but the particles in the coffee will be moving faster.
This is because the lake, being a large body of water, contains much more thermal energy overall due to its volume, even though the individual water particles in the coffee, which is hot, will be moving faster than those in the cold lake water.
Use the image to answer the question. The gallium in the image is melting in the person’s hand. Which changes will occur on a microscopic level? (1 point) Responses The gallium atoms will gain kinetic energy. The gallium atoms will gain kinetic energy. The gallium atoms will gain potential energy, moving freely from each other. The gallium atoms will gain potential energy, moving freely from each other. The gallium atoms will increase in temperature. The gallium atoms will increase in temperature. The gallium atoms will be moving faster on average. The gallium atoms will be moving faster on average. Skip to navigation
The correct response is: The gallium atoms will gain kinetic energy.
As gallium melts when placed in the person's hand, the heat from the hand transfers to the gallium, causing the gallium atoms to gain kinetic energy and move more freely, leading to the melting process.
