1. What is the freezing point of alcohol?
2. What is the boiling point of alcohol?
3. What is the boiling point petrol?
4. What is the freezing point of anti-freeze?
5. Which liquid will change into a gas at 108°C?



Answer :

1. The freezing point of alcohol, specifically ethanol, is around -114 degrees Celsius. At this temperature, ethanol changes from a liquid state to a solid state.

2. The boiling point of alcohol, again referring to ethanol, is approximately 78 degrees Celsius. This is the temperature at which ethanol changes from a liquid to a gas.

3. The boiling point of petrol, or gasoline, can vary slightly depending on the composition, but typically ranges from about 30 to 200 degrees Celsius. The specific boiling point of petrol depends on the blend of hydrocarbons present in the fuel.

4. The freezing point of antifreeze, which is typically a mixture of water and ethylene glycol, is usually around -37 degrees Celsius. Antifreeze is designed to prevent freezing in a vehicle's cooling system, allowing it to function properly in cold temperatures.

5. A liquid that will change into a gas at 108 degrees Celsius could be water. At this temperature, water reaches its boiling point and transitions from a liquid state to a gaseous state, forming steam.
