Question

1.)The internal energy of a substance is defined as

the potential energy of all particles which make up the substance.

the chemical energy of all particles which make up the substance.

the thermal energy of all particles which make up the substance.

the sum of the potential and kinetic energy of all particles which make up the substance.

the kinetic energy of all particles which make up the substance.

2.)Calculate U of a gas for a process in which the gas absorbs 9 J of heat and does 25 J of work by expanding.

3.)The energy associated with the motion of a speeding bullet is called _____.

the potential energy of all particles which make up the substance.

the chemical energy of all particles which make up the substance.

the thermal energy of all particles which make up the substance.

the sum of the potential and kinetic energy of all particles which make up the substance.

the kinetic energy of all particles which make up the substance.

1. the sum of the potential and kinetic energy of all particles which make up the substance.

2. U = 9 J (internal enrgy will be only which absorb for work)

3. Kinetic enrgy (during movement potetnial energy Zero.)
