Automobiles are powered by an internal combustion engine. The engine converts the chemical energy in gasoline and oxygen into heat, that is then transformed into the propulsive energy that moves the automobile. Which statement most accurately describes the energy used to move the automobile ?
B
A Kinetic energy is stored by chemical and thermal energy
The chemical energy stored in gasoline and oxygen is converted into thermal energy and is then transformed into mechanical energy.
Thermal energy is transformed into chemical energy and is then converted into mechanical energy
The chemical energy in gasoline and oxygen is converted into heat.
C
D

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
