Answer:
This is a desert because there is little precipitation for plant and animal life to thrive.
Explanation:
Tundra is harsh environment because of its cold temperature, so it's definitely not too hot. Swamp temperature should be not too cold or hot. The rainforest should have abundant plant and animal life.
Desert has very low precipitation and low moisture so that not much water can be found around. Water is vital for any plant or animal. Water also helps regulate temperature and make the fluctuation in the environment extreme. The temperature around the desert can be really high at daylight and low at night.

Answer:</h3>
= 19.712 kJoules

Explanation:</h3>
- Heat of vaporization refers to the amount of heat required to change a unit mass of a substance from liquid to gaseous state without change in temperature.
To calculate the amount of heat, we use,
Amount of heat = Mass × Heat of vaporization
Q = m×Lv
Given;
Mass of liquid Zinc = 11.2 g
Lv of liquid Zinc = 1.76 kJ/g
Therefore;
Q = 11.2 g × 1.76 kJ/g
= 19.712 kJ
Thus, the amount of heat needed to boil 11.2 g of zinc is 19.712 kilo-joules.
