Answer : Option A) The liquid turns to a gas.
Explanation : When the hydrogen bonds between the molecule of water breaks, it produces hydrogen and oxygen gases. As the intermolecular forces of attraction between the molecule is broken, it gets enlarged and therefore the phase changes into gas. Breaking of intermolecular forces of attraction between the atoms of the molecule results into phase transition.
Answer:
I. x = -3
II. y = -2
Explanation:
Given the following algebraic equation;
.........equation 1
..........equation 2
We would solve the algebraic equation using the substitution method
From equation 1;
.....equation 3
Substituting eqn 3 into eqn 2, we have;
Multiplying all through by 5
Rearranging the equation, we have:
x = -3
Next we find the value of y;
From eqn 3;
Substituting the value of "x" into the equation, we have;
y = -2
