What is the correct order of steps Tina should follow to correctly perform her experiment?
Look at the graphic and the chart. Which is the correct direction of heat transfer?
Explain the difference between conduction and convection.
Conduction involves heat going in all directions while heat rises with convection.
Heat moves in all directions for convection, but it rises for conduction.
Heat rises for convection and travels thru liquids and gases. Conduction travels thru solids and liquids but must be physically touching.
Thermal energy travels thru solids for both conduction and convection; however, conduction involves direct contact.
Ice cubes are placed in a glass of water that is at room temperature. Which statement best describes the temperature of the water after 10 minutes?

The temperature decreases because some of the ice’s heat is lost to the water.
The temperature increases because some of the coolness of the water is absorbed by the ice.
The temperature increases because some of the coolness of the ice is absorbed by the water.
A student dissolves an antacid tablet in water at different temperatures and records the data in a table. Which statement is best supported by the data?
Temperature has no effect on the time it takes for the antacid tablets to dissolve.
The warmer the water, the longer it takes for the antacid tablets to dissolve.
The colder the water, the longer it takes for the antacid tablets to dissolve.
The colder the water, the faster the antacid tablets dissolve.
Potassium nitrate is a salt that dissolves in water. A teacher fills three beakers with 100 mL of water at different temperatures (20 degrees Celsius 40 degrees Celsius, and 60 degrees Celsius) and adds salt to each beaker in small amounts until no salt can be dissolved.

Water dissolves salts only at high temperatures.
The solubility of the salt increase with temperature.
More salt dissolves in water at lower temperatures.
The salt needs large amounts of water to be dissolved.
