How much thermal energy is in 100 grams of water at 50 degrees Celsius

Ymorist [56]

when the thermal energy is the energy contained within a system that is responsible for its temperature.

and when the thermal energy is can be determined by this formula:

q = M * C *ΔT

when q is the thermal energy

and M is the mass of water = 100 g

and C is the specific heat capacity of water = 4.18 joules/gram.°C

and T is the difference in Temperature = 50 °C

So by substitution:

∴ q = 100 g * 4.18 J/g.°C * 50

= 20900 J = 20.9 KJ

Exponential growth can lead to decreasing the population size, which represents an example of a NEGATIVE feedback loop. This control mechanism (negative feedback) is common in nature.

Negative feedback is a homeostatic self-regulatory process by which the output of a given system is fed back in order to reduce its internal fluctuations.

In a negative feedback, an amplified output from the system (e.g., in this case, a sudden increased population size) leads to its self-inhibition.

This control mechanism (negative feedback loop) helps to maintain the homeostatic balance of the entire system in order to reach a set point.
