Question

Answer this correctly.
You fill a glass with room temperature water from the sink and then place it in the freezer. After a few hours, you take the glass out and the water is now a solid. In two to three sentences MAX explain what happened to the water in the glass as the temperature decreased. key words to include for full points: kinetic energy, thermal energy, temperature and heat.

As the glass of water was placed in the freezer, the lower temperature of the freezer removed thermal energy from the water, causing its temperature to decrease. As the temperature dropped, the kinetic energy of the water molecules decreased, leading to their gradual transition from a liquid state to a solid state, resulting in frozen ice.
Answer this correctly.
A graduated cylinder contains 50 mL of water. You carefully place a rock into the cylinder, causing the water level to rise to 70 mL. if the mass of the rock is 100 grams, explain how to calculate the density of the rock in two to four sentences. describe each step of the process and provide the final density value for full points. You must write your answer explaining all steps, write it in 3 sentences or less.

To calculate the density of the rock, first determine its volume by measuring the change in water level in the graduated cylinder, which is 70 mL - 50 mL = 20 mL. Then, use the formula for density, which is mass divided by volume: density = mass/volume, so density = 100 grams / 20 mL = 5 grams/mL. Therefore, the density of the rock is 5 grams/mL.
