Answer:
d. steam-water equilibrium at 373 K
Step-by-step explanation:
At one atmospheric pressure , the boiling point of water is 100°C or 273+100 = 373 K in kelvin temperature scale.
so at this temperature vapor pressure of water and steam are in equilibrium .
Answer:
C
Step-by-step explanation:
A is incorrect because -3.1 is rational.
B is incorrect because 1.14 repeating is rational.
C correct because everything that can be expressed as a fraction is on the left and everything that can't is on the right.
D is incorrect because pi is irrational.
I think it is...
F(1)=1(2)-1+2 which equals -1
I'm not sure tho
Answer:
Difference in the lengths of the polygons is (x + 7) units.
Step-by-step explanation:
Lengths of the given polygon = (7x + 2) units and (6x - 5) units
Therefore, difference in the given lengths = (7x + 2) - (6x - 5)
= (7x - 6x) + (2 + 5)
= x + 7
Therefore, difference in the lengths of the polygons is (x + 7) units.
