Part 1 of 2 Matter is in a liquid state when its temperature is between its melting point and its boiling point. Suppose that some substance has a melting point of - 39.67°C
and a boiling point of 387.32°C. What is the range of temperatures in degrees Fahrenheit for which this substance is not in a liquid state? (Hint: C = 5/9(F-32))
Express the range as an inequality and in interval notation.

The substance will not be in liquid state in range -273.15  

(absolute zero) to -47.42  

and the temperature above 364.76  

Explanation:

The Substance will be in solid state in at the temperature below its melting point and it will be is gaseous state at the temperature above its boiling point. So it will be liquid between melting and boiling point.

Step-by-step explanation:

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.
