Y 185.c 1087.c
Z 20.c 160.c
Which element is liquid state at 311.f?

Answer 1

Answer:

Z

Explanation:

because 311 degree f means 155 degree c

it means it is in liquid state

as its boiling point is 160 and the question is at 155 c

w and z have melting point more than 155 that means it is at solid state

X have boling point 150 it means at 155 it means it is at gasous state
