A. is a neutral substance a pH of 7 describes something of neutral pH where anything less than 7 is an acid and higher is a base
The chemical energy of petrol is converted to heat energy on combustion. The heat energy is converted to kinetic energy by the use of internal combustion engines in vehicles. The law of conservation of energy is maintained in each process.
<h3>What is kinetic energy?</h3>
The kinetic energy of an object is associated with its motion. It can be related to the mass and velocity as
K.E = 1/2 mv²
Given is a diagram of energy conversion due to combustion.
The chemical energy of petrol is converted to heat energy on combustion. The heat energy is converted to kinetic energy by the use of internal combustion engines in vehicles.
The law of conservation of energy states that the energy can neither be created nor destroyed. It can be only converted to one form to the other.
In the given process, the mass decreases but energy remains the same in all forms of energy.
Hence, the law of conservation of energy is maintained in each process

Looks like you need to review through the lesson and take notes as it tells you in the lesson what each of these are.
Answer:
58.44 C
Explanation:
Electric field is found by
Therefore, the charge is


Therefore, required charge is 58.44 C
<h2>Answer: Temperature
</h2>
Temperature is a physical quantity that reflects the amount of heat in a body or medium. This amount of heat is related to the internal energy of a system (thermodynamically speaking), <u>according to the movement (speed) of each of the particles that compose it</u>, this means that it is related to its kinetic energy.
Therefore, the higher the kinetic energy, the higher the thermal energy in the system and the higher the temperature.
