Explanation:
When water is heated up then its molecules move rapidly from one place to another. Hence, kinetic energy of the molecules tend to increase.
Also, K.E = 
where, T = temperature
Therefore, more is the increase in temperature more will be the mean molecular speed change in the water molecules.
As a result, mean molecular speed change increases with increase in temperature and vice-versa.
Answer:
Im not sure what you mean but I hope what I wrote helps you!
The Law of Conservation of Matter says that the amount of matter stays the same, even when matter changes form. Sometimes it may seem that matter disappears during a science experiment, but this law tells us that matter cannot magically appear or disappear, it simply changes from one form to another.

Answer:
it is a weak acid
acid
Explanation:
formaldehyde is a weak acid (pK greater than 13),
Answer:
E = 3.035× 10-¹⁹J = 1.9eV
f = 4.58 × 10¹⁴Hz
Explanation:
wavelength = 6.55 × 10-⁷m
c = 3 × 10⁸m/s
f = ?
E = ?
a) f = c/wavelength
f = 3 × 10⁸/6.55 × 10-⁷
f = 4.58 × 10¹⁴Hz
b) E = hc/wavelength
E = 6.626×10-³⁴ × 3 × 10⁸/ 6.55 × 10-⁷
E = 3.035 × 10-¹⁹J
1ev = 1.6 × 10-¹⁹J
Therefore E = 3.035/1.6 = 1.9eV
