EMS, Nature of science and heat transfer -Unit 2 Review

Pick the best one to hypothesize sun's heat affects the rate of evaporation

• Have 2 containers with equal amount of water ,Place one container under a lamp and place the other one without a lamp and note the time taken to evaporate

• Have 2 containers with equal amount of water ,Place one container under a tree, place the other one in open area where it gets sunlight and note the time taken to evaporate

• Have 2 containers with equal amount of water ,Place one container under a fan, place the other one in closed room and note the time taken to evaporate

• Have 2 containers with equal amount of water ,Place one container dark room , the other one in open area where it gets sunlight and note the time taken to evaporate

Reena is testing how light affects rate of growth. She has 2 potted plants of same type and size and in same kind of soil . She placed one potted plant under a lamp and the other one not under a lamp and checked the growth in centimeters after a week.

In this experiment, what will be the independent variable

• amount of light provided

• growth rate

• type of plant

• type of soil

Reena has an ice piece in her hand. It is slowly melting. When will be the molecules in it packed together?

• As it is in the liquid state

• As it start evaporating

• When it forms gas

• As it is in the solid state

When you add energy to liquid what happens and name the process

• it changes to solid and the process is called vaporization and evaporation

• it changes to gas and the process is called vaporization and evaporation

• it changes to gas and the process is called sublimation and deposition

• it changes to gas and the process is called freezing and evaporation

What is happening when liquid water changes to ice?

• Energy is added and molecules move faster

• Energy is added and molecules stop moving

• Energy is removed and molecules come closer and stop moving

• Energy is removed and molecules spread apart
