The questions
- A block has a mass of 180 g and a volume of 200 cm³. What is its density in grams per cubic centimetre?
- A plastic toy has a density of 0.8 g/cm³. Placed in water, which has a density of 1.0 g/cm³, the toy will:
- A student dissolves 25 g of sugar in enough water to make 500 mL of solution. What is the concentration in grams per litre?
- Honey flows more slowly than vegetable oil at the same temperature. This means honey has:
- A hydraulic piston has an area of 0.03 square metres. A force of 90 newtons is applied to it. What pressure does it produce, in pascals?
- Compared with particles in a liquid, particles in a gas at the same temperature are. Select all that apply.
- A student keeps adding sugar to a glass of water, and eventually no more will dissolve, however long it is stirred. The solution is now:
- Use the table. About how much more solute dissolves in 100 mL of water at 80 degrees Celsius than at 20 degrees Celsius, in grams?
