The thermodynamic quantity that expresses the extent of randomness in a system is . Question 14 options: entropy bond energy enthalpy internal energy heat flow

Entropy refers to the thermodynamic quantity, which expresses the extent of randomness in a system.  

•The measure of the thermal energy of the system per unit temperature, which is inaccessible for performing useful work is termed as entropy.  

•As work is obtained from ordered molecular motion, entropy is the measure of the molecular randomness, or disorder, of a system.

•It is the thermodynamic quantity, which articulates the degree of disorder in a system.  

•The internal energy of the system supplemented to the product of the volume and pressure is termed as enthalpy.  

•The flow of heat via some system, usually convection is termed heat flow.  

•The energy of the system contained by the system is termed as the internal energy.  

•The amount of energy needed to dissociate a specific bond between two atoms is termed the bond energy.  

Thus, correct answer is entropy.

Explanation:

Entropy is the measure of degree of randomness or disorder of the system.

Bond energy is the energy possessed by a substance by virtue of its bonding of electrons

Enthalpy is the amount of energy absorbed or released in a chemical reaction.

Internal energy is the energy possessed by a body by virtue of rotational, vibrational and transitional modes.

Heat flow is the phenomenon of thermal equilibrium in which heat flows from hotter body to colder body to maintain equilibrium temperature.

what is the general relationship between a galaxy's distance from earth and its speed?

the answer is:

the farther away a galaxy is from us, the faster it is moving away from us.
