Explain the conditions for cloud formation

Clouds form in regions of low pressure. Moist, warm air may flow over a cooler area and the water vapor in that air may condense, forming clouds. There are many possible situations in which water vapor in the air may condense and form clouds. 
Hope this helped you.

Are formed from small drops of water or ice in its liquid state. Can have different shapes and sizes. Are also formed from water vapour, i.e. particles are formed from the cooling of the air, it consumes all the energy and dust from the air, causing the temperature decrease and the so called adiabatic cooling occurs.

hope this helps!

Sugar + oxygen > carbon  dioxide + water + energy  c6h1206 + 6o2 > 6co2 +6h2o + energy  and the numbers after the element symbols are small.     

The answer to this will be from your lab notes/procedure. it would be best to ask another student who participated in the lab as we do not know what was done, what enzyme or if the temperature is celsius or fahrenheit. if i were to guess though i'd say the rate stopped due to enzyme denturing at high temperature
