Answer:
Distance = 200 km
Distance = 204 km
Speed = 77 km/h
Time = 21.42 h
Explanation:
Given:
A.
Speed = 100 km/h , Time = 2 h
Find:
Distance
B.
Speed = 68 km/h , Time = 3 h
Find:
Distance
C.
Distance = 154 km , Time = 2 h
Find:
Speed
D.
Distance = 1500 km speed = 70 km/h
Find:
Time
Computation:
Speed = distance / time
A.
Distance = 100 x 2
Distance = 200 km
B.
Distance = 68 x 3
Distance = 204 km
C.
Speed = 154 / 2
Speed = 77 km/h
D.
Time = 1500 / 70
Time = 21.42 h
The graph of the relationship between the volume and temperature of an enclosed gas is ; ( A ) It is a straight line with a positive slope showing that an increase in temperature results in an increase in volume
According to Charlies' law at constant pressure, the volume of a gas ( enclosed gas ) is directly proportional to it's temperature ( kelvin temperature ) given that the amount of the enclosed gas is kept constant.
Therefore the graph showing the relationship between the volume and temperature will be an straight line and the slope will be a positive slope.
Hence we can conclude that The graph of the relationship between the volume and temperature of an enclosed gas is a straight line with a positive slope showing that an increase in temperature results in an increase in volume

In order to perform the experiment, in identifying the
temperature of different kinds of liquid freeze—the needed equipment is the
thermometer. It is because the thermometer is an equipment that helps in
determining a temperature. The variable in the experiment would be the
temperature as this is not consistent for the effects or outcome will likely
change.
Nh3 is ammonia. Nh4+ is ammonium ion. NRH2 is primary amine, R2NH is secondary amine, R3N is tetiary amine. R is alkyl group
Answer:
