Answer:

1125 mL

Explanation:

This is very much like a math problem. You have to set it up as a proportion:

The setup "template" should be mL/m HCl.

\frac{225}{2.4}=\frac{x}{12}

Now, you cross multiply:

225*12 = 2.4*x

2700 = 2.4x

Divide:

x = 1125

Why is the vapor pressure of a warm pale higher than the vapor pressure of a cold lake
levacccp [35]

The vapor pressure of a warm pale higher than the vapor pressure of a cold lake because Warm water evaporates more quickly.

Hence, Option B is correct answer.

<h3>What is Evaporation ? </h3>

The process in which a liquid or solid is converted into vapour is called Evaporation. When water gains the heat energy then it changes in to gas. When the temperature increases it speeds up the rate of evaporation.

The temperature of warm water increases, the kinetic energy of the warm water molecule also increases.

Thus from the above conclusion we can say that The vapour pressure of a warm lake is higher than the vapor pressure of a cold lake because Warm water evaporates more quickly.

Hence, Option B is correct answer.

Objects can be charged when electrons move from one object to another by direct contact 1.Charging by conduction (contact) 2.Cha
stellarik [79]

Answer:

Charging by conduction (contact)

Static electricity charging by induction

Explanation:

A body can be charged when another body is made to touch it such that charges are transferred from a charged body to an uncharged body. This is known as charging by contact.

A body can also be charged by induction. In this case, a charged body is only brought near an uncharged body without really touching the uncharged body. Charges are transferred without physical contact of the bodies.
