Question

identify the physical states of 1 2 3 at the room temperature on the basis of following data
1 melting point -40 boiling point 360
2 melting point 100 boling point 900
3meltingpoint -200 boiling point -160​

Answer 1

Answer:

1 liquid

2 solid

3 gas, temperature less melting point = solid

room temperature = 25°C

Answer 2

Answer:

1=liquid

2=solid

3=gas

Explanation:

as the avg. room temperature is about 24℃ the substance will be liquid if it's melting point is below 24℃ and solid if melting point is above 24℃

if the boiling point is less than the room temperature the substance will be gas
