Solubility at 100 °C = 480 g / 100 mL of solution =: saturated solution
The proportion 240 g / 50 mL is equal to the saturated ratio 480 g / 100 mL
Then, 240 g of sugar in 50 mL of boiling water will make a saturated solution.
Answer: saturated
A. The kinetic energy of gas particles is higher in hot food than in cold food.
Explanation:
The smell of a hot food moves faster than the smell of a cold food because the kinetic energy of gas particles is higher in hot food than in cold food.
Let us establish that the smell of the food perceived are gases from the food.
- Both hot food and cold food emits these gases that tinkers our olfactory nerves.
- Hot food produces a hot gas.
- The higher the temperature the more kinetic energy it possess.
- This makes the gases more dispersed and it spreads faster.
- The cold food produces gas at a lower kinetic energy.

The gamma-ray emitting technetium-99m (metastable) is widely used for medical diagnostic studies. Several chemical forms are used to image different parts of the body. Technetium is a remarkable corrosion inhibitor for steel, and adding very small amounts can provide excellent protection.
hope that helps you :)
