Match the definition to the correct term. a substance that is released I into the atmosphere the energy that holds protons and neutrons together in an atomic nucleus renewable energy from plants and animals a. nuclear energy b. emission c. biomass
What explains the reason for having to cook food for longer at high altitudes? The atoms that make up the food behave differently at lower atmospheric pressure. The lower atmospheric pressure causes the boiling temperature to be lower. The food molecules stick together more and require more energy to separate them.
As the temperature of the gas in a balloon decreases, which of the following occurs? The volume of the balloon increases. The average kinetic energy of the gas decreases. The gas pressure inside the balloon increases. all of the above
How is radiation different from convection and conduction? It can travel through empty space. It can travel through matter. It can travel through water.
Match this description with the term that closely matches it: Process that lowers the average speed of molecules in a liquid.
What does one prolonged blast emitted by Boat A using an efficient sound producing device indicate?
Question: When rounding a curve a car tends to: Options: Speed up. Move to the inside of the curve. Stay in the center of the lane. Move to the outside of the curve.
What is the relationship between velocity and acceleration? Acceleration is the change in velocity over time. Velocity is the change in acceleration over time. Velocity and acceleration are equal and opposite. Velocity and acceleration have nothing to do with each other.
19. The process by which atomic nuclei spontaneously decay is called relative dating radioactivity erosion deposition 20. The time it takes for 50 percent of the nuclei in a radioactive sample to decay to its stable isotope is called the daughter product geologic time the half-life the half-time 21. The scientist who developed the theory of evolution was Harry Hess James Hutton Charles Darwin William Smith
