Some plants also have large leaves to soak up nutrients and water, very helpful in this biome since it rains a lot. - Having some needles cased in wax, withstand cold temperatures and losing water from their leaves. - Having thin bark and shallow roots enables trees to withstand fire.
The dependent variable would be the heart rates of her classmates.
Answer:
i dont think i can explain it easy sorry
Explanation:
The first law, also known as Law of Conservation of Energy,Thermal energy is the internal energy of an object due to the kinetic energy states that energy cannot be created or destroyed in an isolated system. | Nuclear energy originates from the splitting of uranium atoms a process called fission. This generates heat to produce steam, which is used by a turbine generator.
then the chemical bonds are broken, | the potential energy is released in the form of kinetic energy or energy of motion and heat or non useable energy. The kinetic energy is used to do work. | Objects have mechanical energy if they are in motion and or if they are at some position relative to a zero potential energyposition for example, a brick held at a vertical position above the ground or zero height position. A moving car possesses mechanical energy due to its motion
The second law of thermodynamics states that the entropy of any isolated system always increases.
Answer:
110 kg
Explanation:
Density = Mass / Volume ===> Mass = Density x Volume
Now follow the given:
- Density = 2 kg/L or 2000 g/L
- Volume = 55 L
Apply the rule:
Mass = 55 L x 2 kg/L = 110 kg or 110000 g. ( Liters is cancelled by Liters).
Answer: The correct answer is-
liquid to solid.
The term exo in exothermic means outside the system whereas thermic means heat.
Exothermic process can be described as any chemical reaction that liberates energy in the surrounding in the form of heat.
In other words, when heat is liberated in the environment in a chemical reaction, it is said to be an exothermic reaction/process.
When liquid phase changes to solid phase (such as water to ice), heat is released/liberated in the surrounding.
Thus, it is an example of exothermic process.
