Answer:

1. The warm air over the land will rise throughout the day, causing low pressure at the surface. ... The wind will blow from the higher pressure over the water to lower pressure over the land causing the sea breeze. The sea breeze strength will vary depending on the temperature difference between the land and the ocean.

2. The cold water becomes warm on a hot summer afternoon because the sun's radiation will heat up the water. As the surroundings of the cold water is warmer, the heat is transferred to the cold water till both attain equal temperature.

3. Glass has a very low coefficient of thermal expansion. This is the reason why thermometer bulb or for a matter of fact entire thermometer is made up of glass. Due to low coefficient of thermal expansion, when the thermometer undergoes a large temperature change it will have minimal change in dimensions.

if you won't mark as brainliest also it's ok.
