Question

1. calculate the density of a liquid with a volume of 30 cm³ and a mass of 150g. (1)
2. state 2 properties of a solid. (1)

Explanation:

Question 11

Step1: Recall density formula

The formula for density $
ho=\frac{m}{V}$, where $m$ is mass and $V$ is volume.

Step2: Substitute values

Given $m = 150g$ and $V=30cm^{3}$, then $
ho=\frac{150g}{30cm^{3}}$.

Step3: Calculate density

$
ho = 5g/cm^{3}$

Solids have a definite shape and a definite volume. These are fundamental physical - state properties. A definite shape means they maintain their form without a container, and a definite volume means they occupy a fixed amount of space.

Answer:

$5g/cm^{3}$
