Pitanje 1

Which of the following is a not a sign of a chemical change?

Light is emitted

Color stays the same

Change in temperature

Gas is produced

Obavezno

Pitanje 2

What is endothermic reaction in simple terms?

it emits light during reaction

it involves a physical change

it absorbs heat from the surroundings

it heats up spontaneously

Obavezno

Pitanje 3

What is the main difference between endothermic and exothermic reactions?

Endothermic involves physical changes, exothermic doesn't

Endothermic reacts faster than exothermic

Endothermic absorbs heat, exothermic releases heat

Endothermic releases heat, exothermic absorbs it

Obavezno

Pitanje 4

Categorize these reactions as exothermic or endothermic

Burning of wood
Melting of ice
Photosynthesis in plants
Combustion of gasoline

Exothermic
Endothermic

Obavezno
