Pitanje 1

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

Gas is produced

Color stays the same

Light is emitted

Change in temperature

Obavezno

Pitanje 2

What is endothermic reaction in simple terms?

it absorbs heat from the surroundings

it involves a physical change

it heats up spontaneously

it emits light during reaction

Obavezno

Pitanje 3

What is the main difference between endothermic and exothermic reactions?

Endothermic releases heat, exothermic absorbs it

Endothermic absorbs heat, exothermic releases heat

Endothermic reacts faster than exothermic

Endothermic involves physical changes, exothermic doesn't

Obavezno

Categorize these reactions as exothermic or endothermic

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

Exothermic
Endothermic

Obavezno
