Answer: In order to forecast the weather, they study high and low pressure systems and the boundaries between them which is why they are called weather fonts
Explanation:
The hotter an object is, the faster the motion of the molecules inside it. Thus, the heat of an object is the total energy of all the molecular motion inside that object. Temperature, on the other hand, is a measure of the average heat or thermal energy of the molecules in a substance.
Answer:
There are several ways of measuring the rate of photosynthesis in the lab. These include:
the rate of oxygen output
the rate of carbon dioxide uptake
the rate of carbohydrate production
These are not perfect methods as the plant will also be respiring, which will use up some oxygen and carbohydrate and increase carbon dioxide output.
Several factors can affect the rate of photosynthesis:
light intensity
carbon dioxide concentration
temperature
The amount of chlorophyll also affects the rate of photosynthesis:
plants in lighting conditions unfavourable for photosynthesis may synthesise more chlorophyll, to absorb the light required
the effects of some plant diseases affect the amount of chlorophyll, and therefore the ability of a plant to photosynthesise

Answer:
Explanation:
We can convert the formula units to moles and then use the molar mass to find the mass.
1. Moles of Pb(MnO₄)₂
2. Mass of Pb(MnO₄)₂
Instead, they are created when magma cools and hardens —> the temperature contributes as the magma would be at extreme heat while it need a cooler temperature to harden and mold
