Answer

A

Step-by-step solution

3 steps

Part iv

The best description of the Particle Theory of Matter is that all matter is made up of tiny particles that are constantly moving.
The correct option is A.

Part b· 3 steps

  1. Recall the formula for pressure.

    P=FAP = \frac{F}{A}

    where PP is pressure, FF is force, and AA is area.

  2. Substitute the given values into the formula.

    Given F=500 NF = 500 \text{ N} and A=2 m2A = 2 \text{ m}^2.

    P=500 N2 m2P = \frac{500 \text{ N}}{2 \text{ m}^2}

  3. Calculate the pressure.

    P=250 N/m2P = 250 \text{ N/m}^2 P=250 PaP = 250 \text{ Pa}

    The pressure exerted by the gas on the wall is 250 Pa\boxed{\text{250 Pa}}.

Part c

A sealed bag of chips appears puffed up at high altitudes because the external atmospheric pressure decreases significantly. The air inside the bag was sealed at a lower altitude with higher atmospheric pressure. The lower external pressure at high altitudes allows the higher internal pressure to push outwards, causing the bag to expand.

Part d

The correct statement about purity is that 24-karat gold is an example of a substance with high purity. 24-karat gold is considered 100% pure gold.
The correct option is B.

Q4 (a)(i)
When magnesium ribbon burns in air, it reacts with oxygen to form magnesium oxide. The white ash left behind in the watch glass is Magnesium oxide.
