What is the relationship between kinetic energy and negative values in physics?
In physics, kinetic energy is always a positive value because it represents the energy of an object in motion. Negative values are not typically associated with kinetic energy in a physical context.
Is it possible for power to have a negative value?
Yes, power can have a negative value when it represents a decrease in energy or influence.
Is it possible for potential energy to have a negative value?
Yes, it is possible for potential energy to have a negative value. This can occur when the reference point for measuring potential energy is set at a higher level than the actual position of the object.
Is it possible for energy to have a negative value?
Yes, in certain contexts, energy can have a negative value. This can occur in physics when calculating potential energy or in quantum mechanics when considering energy levels below the zero-point energy.
Is it possible for gravitational potential energy to have a negative value?
Yes, gravitational potential energy can have a negative value when an object is located below a reference point, such as the ground level.

What is the expectation value of kinetic energy for a hydrogen atom?
The expectation value of kinetic energy for a hydrogen atom is -13.6 eV.
Is it possible for the change in enthalpy, represented as H, to have a negative value in a chemical reaction?
Yes, it is possible for the change in enthalpy (H) to have a negative value in a chemical reaction, indicating that the reaction releases heat energy.
Is it possible for the specific heat of a substance to have a negative value?
No, it is not possible for the specific heat of a substance to have a negative value.
Why kinetic energy is always positive?
Kinetic energy is always positive because it is a measure of the energy of an object in motion. Regardless of the direction of motion, the velocity term in the kinetic energy equation is squared, which ensures that the kinetic energy value is positive.
What change would occur in the kinetic energy of vapor if a container of vapor is placed at 0 Kelvin?
At 0 Kelvin, the kinetic energy of the vapor would decrease to the minimum possible value as all molecular motion stops. This is known as absolute zero, and at this temperature, particles have minimal movement and consequently have minimal kinetic energy.
Measure of the average value of the kinetic energy of the molecules in a substance?
Temperature is a measure of the average value of the kinetic energy of the molecules in a substance. As temperature increases, the kinetic energy of the molecules also increases, leading to higher speeds and more rapid movement.
All the molecules of a substance possess the average kinetic energy value. True False?
True. In a substance, all molecules possess the average kinetic energy value because temperature is a measure of the average kinetic energy of the particles in a substance.
