Answer:
Air temperature is not accurate but it can measure by the air is cold or hot
Hope this will help you
P = mv, where p is momentum, m is mass in kg and v is velocity in m/s
<u>Answer:</u>
Vinegar is made from the fermentation of dilute alcoholic liquids into acetic acid.
<u>Explanation:</u>
Vinegar is a sour tasting liquid which is produced by the fermentation of dilute alcoholic liquids such as cider, wine and beer.
It is a solution of acetic acid which is more formally also known as ethanoic acid.
The concentration of acetic acid in vinegar is variable as it is used for different purposes with different concentrations.

Answer:
Both B and D are correct.
Explanation:
B + H₂O ⇌ BH⁺ + OH⁻
If you add more products, the position of equilibrium will shift to the left to decrease their concentrations (Le Châtelier's Principle). The concentration of reactants will increase, but the equilibrium concentrations of products will also be higher than they were initially.
A is wrong. The equilibrium constant is a constant. It does not change when you change concentrations.
C is wrong. Per Le Châtelier's Principle, the concentrations must change when you ad a stress to a system at equilibrium.
(This is a poorly-worded question. "They" are probably expecting answer D.)
