Answer:
The energy difference between the ground and excited state and temperature has the following effect on the excited-state population: As the energy difference between the ground state and excited state decreases, the excited-state population DECREASES. As the temperature of the flame increases, the excited-state population INCREASES.
Step-by-step explanation:
When one or more electrons in an atom has an increase in energy than an unoccupied state, it means the atom is in an excited state. If the atom is not in an excited state, it is considered to be in the ground state.

Determine the distance (y) covered by his car
First, we calculate the distance walked.
This is calculated as follows;
This means that he walked 4.5 km
The total distance can be expressed as a sum of distance covered while walking and distance covered by car.
i.e.
Make Car the subject
This gives
<em>Hence, his car travelled 15.5km</em>
