Answer:
n = 3.0 moles
V = 60.0 L
T = 400 K
From PV = nRT, you can find P
P = nRT/V = (3.0 mol)(0.0821 L-atm/K-mol)(400 K)/60.0L
P = 1.642 atm = 1.6 atm (to 2 significant figures)
Explanation:
Answer:
There are 0.0305 calories in 0.128 joules
Explanation:
Given that,
Heat absorbed, Q = 0.128 J
We need to find the heat energy absorbed in calories.
We know that the relation between joules and calories is as follows :
1 calorie = 4.184 J
1 J = (1/4.184) J
So,
So, there are 0.0305 calories in 0.128 joules

Milk is an example of solid emulsion. Hence, option D is correct.
<h3>What is emulsion?</h3>
An emulsion is defined as a colloid consisting of two or more non-homogenous type of liquids in which one of the liquid contains the dispersion of the different form of liquids.
Emulsion consist of a dispersion of two liquids that are immiscible with each other.
One of the liquids act as the dispersion medium and the other will act as the dispersed phase.
Emulsions are colloids in which both the dispersed phase and dispersion medium are liquids.
Types of Emulsion:
- Oil in water (O/W)
- In this type of emulsion, the oil will be the dispersed phase and water will be the dispersion medium.
- Example of o/w emulsion is milk.
2. Water in oil (W/O)
- In this type, water will be the dispersed phase and oil will be the dispersion medium.
- Margarine is an example of water in oil emulsion.
Milk is an example of solid emulsion. Hence, option D is correct.
