MOCK YEAR 9 Chemistry and Physics

Question 1

What is Force measured in?

Answer 1

Newtons (N)

Question 2

What’s pressure measured in?

Answer 2

Pascal Pa

Question 3

True or False: Presure = mass x Acceloration

Answer 3

False Pressure is calculated by the formula Force/m^2

Question 4

What’s mass Divide Volume sum for?

Answer 4

Density

Question 5

What do we call the force if the resultant force is zero?

Answer 5

Equlibriam

Question 6

Name three forms of Non- contact Forces?

Answer 6

Gravity Magnetism and air resistant

Question 7

What do we do to increase the pressure?

Answer 7

Reducing Surface area

Question 8

What do barometers measure?

Answer 8

Pressure

Question 9

How to calculate Pressure difference?

Answer 9

Density Divide Height Divide Gravitational Constant

Question 10

How igneous rocks formed?

Answer 10

When lava cools and solidifies causing crystals and interlocking grains

Question 11

Are extrusive igneous rock have large crystals?

Answer 11

No

Question 12

What’s a sedimentary rock?

Answer 12

Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at the Earth’s surface, followed by cementation. Sedimentation is the collective name for processes that cause these particles to settle in place

Question 13

How is a metamorphic rock formed?

Answer 13

Pressure and heat around the main vent Marble

Question 14

How does a microphone work?

Answer 14

Sound enters the microphone causing it to move the diaphragm causing the coil to move to create a current creating the louder sound

Question 15

What’s energy measure in?

Answer 15

Joules J

Question 16

What’s the formula for Work Done?

Answer 16

Force x Distance (M)

Question 17

Calculate the gravitational Potential energy for 10 Grams, Earth’s Gravitational Constant, and 10 Meters high?

Answer 17

0.98J

Question 18

Write down each of the Pressure, Area, and Force formulas?

Answer 18

Pressure = Force/Area(m^2) Force = Pressure x Area(m^2) Area(m^2) = Force / Pressure

Question 19

What happens when a rock is chemically weather?

Answer 19

When it rains in the sea it captures carbon dioxide and makes carbonic acid and then reacts with the calcium carbonate forming calcium bicarbonate.

Question 20

Name two metamorphic rocks?

Answer 20

Marble and Quartz.

Question 21

Where on the periodic table would you find the alkali metals?

Answer 21

The first Colum.

Question 22

What’s group 7 on the periodic table?

Answer 22

Halogens.
