Answer:
abiotic components are non-living chemical and physical factors in the environment which affect ecosystems. Biotic describes a living component of an ecosystem
Explanation:
Answer:
When the average kinetic energy of the molecules goes up (a rise in temperature), the average speed of the molecules increases. And lower average kinetic energy of the molecules means they have lower speed. When heat (energy) goes into a substance one of two things can happen:
Explanation:
If the temperature is increased, the average speed and kinetic energy of the gas molecules increase. ... If the gas volume is decreased, the container wall area decreases and the molecule-wall collision frequency increases, both of which increase the pressure exerted by the gas (Figure 1). Avogadro's law.
Explanation:
In balancing chemical equations, the law of conservation of matter must be strictly obeyed.
By the virtue of this, the following steps are usually taken:
- First identify the atoms on each side of the expression. This to know the number of species to balance.
- Then count the atoms on each side.
- Then using appropriate number as the coefficients, increase the atom on each side until there are equal numbers on both sides.
- Finally, check to make sure we have the same number of each type of atom on each side.
