Types Of Explosion

Question 1

All explosions

Answer 1

Sudden increase in volume due to the release of the nitrogen gas and a huge transfer of energy to the surrounding

Question 2

Physical change

Answer 2

No new substances were made

Can cause natural explosions such as volcanos and geysers.

Question 3

Chemical change/reaction

Answer 3

Atoms in the reactants are rearranged to form new products with different properties

E.g. Hydrogen reacts with oxygen to make water

Question 4

Particle theory

Answer 4

The forces of particles hitting the walls of containers cause pressure pin gases.

Question 5

Gas pressure is increased by

Answer 5

Increasing the number of gas particles ( more particles hit the surface

Increasing he temperature ( particles move faster and hit more often)

Decreasing the size of the container ( so particles hit the surface more often)
