Answer:
Evaporation is the method of separating a solid (solute) from a homogeneous solution.
in this method, the solution is heated until the solvent gets evaporated in the form of vapor and the solute is left behind as residue.
Answer:
is the solubility of nitrogen gas in a diver's blood.
Explanation:
Henry's law states that the amount of gas dissolved or molar solubility of gas is directly proportional to the partial pressure of the liquid.
To calculate the molar solubility, we use the equation given by Henry's law, which is:

where,
= Henry's constant = 
= partial pressure of nitrogen
(Raoult's law)



is the solubility of nitrogen gas in a diver's blood.
Answer:
16 N
Explanation:
The ratio of output force to the input force is called mechanical advantage of the lever. Also, the ratio of input arm distance to the output arm distance is called mechanical advantage of the lever.
We have,
Input force = 8 N
Input arm distance = 6 m
Output arm distance = 3 m
We need to find the resulting output force. So,

So, the resulting output force is 16 N.
Answer:
The correct option is: Cost of materials used in manufacture
Explanation:
There are two types of costs of an object: the internal costs and the external costs.
The internal cost of an object is the direct monetized cost. It refers to the cost involved in the <u>production or manufacturing of a given objec</u>t. Example: labor, <u>material required</u>, equipment, energy, and overhead expenses.
