Science Assessment

RG208001

The chemical energy of the products of photosynthesis is greater than the chemical energy of the reactants (item includes bar graphs).

30%

RG181001

Measuring an increase in temperature during a chemical reaction is an indicator that the chemical energy of the reactants is greater than the chemical energy of the products.

28%

RG199001

During rusting, the substances have less chemical energy after the reaction because some energy was transferred out of the system.

24%

RG209001

The chemical energy of the products of cellular respiration is less than the chemical energy of the reactants (item includes bar graphs).

23%

RG070003

A cold pack has more chemical energy after the salt inside it dissolves. When the salt dissolves, some energy is transferred from the surroundings to the cold pack and converted into chemical energy.

21%

RG173002

An increase in temperature indicates that the amount of chemical energy decreased during the reaction.

19%

RG182001

Measuring an decrease in temperature during a chemical reaction is an indicator that the amount of chemical energy increases.

18%

RG030003

A heat pack has less chemical energy after a reaction occurs inside the pack because some of its energy was transferred to a skier’s hands.

17%

RG184001

When an instant cold pack is used, energy is taken in because the temperature of the surroundings decreases.

14%

RG210001

If the chemical energy of the products of a chemical reaction is greater than the chemcial energy of the reactants, energy was taken in from the surroundings.

12%

RG211001

If the chemical energy of the products of a chemical reaction is less than the chemcial energy of the reactants, energy was released to the surroundings.
