Consider the temperature versus time graph below mc019-1.jpg at what temperature is the substance a heated gas? (a)at 100°c (b)below 0°c (c)above 100°c (d)between 0°c and 100°c

The state of a substance depends upon the nature of substance

a substance is a gas after its boiling point

a substance is heated gas above its boiling point

so if boiling point of substance (like water) is 100°C then the substance will be heated gas above 100°C

for water

a) below 0°C : it will be solid

b) at 100°C : it will have an equilibrium between liquid and gas

c) between 0°C to 100°C : it will liquid

the answer is the first option

explanation:

just googled it m8. not that hard
