Explanation

The freezing (or melting) point of ice on the Fahrenheit scale is 32°F.

This is the temperature at which ice turns from a solid to a liquid. 

The Fahrenheit scale also defines the boiling point of water as 212°F.

A change of 1°F on the Fahrenheit scale is less than a 1°C change on the Celsius scale.

Explanation

• Diphtheria is a bacterial infection that primarily affects the throat and nasal passages.
• It can cause severe inflammation and swelling in the throat, leading to difficulty breathing and swallowing.
• If left untreated, diphtheria can lead to serious complications, such as respiratory failure and heart problems.

Explanation

Wind blows from areas of high pressure to areas of low pressure.

This is because air molecules move from areas of higher concentration (high pressure) to areas of lower concentration (low pressure) to equalize the pressure difference.

This movement of air is what we feel as wind.

Explanation

When outside temperatures are low and there is moisture in the air, small ice crystals are formed.

On their own they are tiny, but when they collide they stick to each other and make snowflakes.

When lots of these particles join together they get heavier and once they are heavy enough they fall to the ground as snow.
