Power is defined in physics as the quantity of energy transported or transformed per unit of time. To calculate power, divide the amount of energy transferred by time.
Power is defined in physics as the quantity of energy transported or transformed per unit of time. The watt is the unit of power in the International System of Units, equivalent to one joule per second. Power is also referred to as activity in ancient writings. A scalar quantity is a power.
The formula for power is given as the ratio of energy transferred to the time taken.
Its SI unit is Watt, while the SI units for energy and time are seconds. Therefore, we can write,
Power = Energy transfer / Time taken
Joule = Watt / Second
Hence, To calculate power, divide the amount of energy transferred by time.

Flammability
Reaction with bases
Solubility
Reaction with oxygen
Answer:
The correct answer is C) Solubility
Explanation:
Solubility is the example of a physical property from the given options, as it can be observed and measured without changing the substance's chemical identity.
The question is asking which of the listed options is an example of a physical property. A physical property is a characteristic of matter that can be observed or measured without changing the substance's chemical identity. Among the choices given - flammability, reaction with bases, solubility, and reaction with oxygen - solubility is a physical property. This is because solubility refers to a substance's ability to dissolve in a solvent, which can be observed without causing a chemical reaction. On the other hand, flammability and reaction with bases or oxygen are chemical properties, as they describe a substance's ability to react and form new substances.
