Answer:
Generally, a gas behaves more like an ideal gas at higher temperature and lower pressure, as the potential energy due to intermolecular forces becomes less significant compared with the particles' kinetic energy, and the size of the molecules becomes less significant compared to the empty space between them

Answer:
The "graduated cylinder" is measuring a "volume of water" in "milliliters".
Option: D
Explanation:
Measuring of "liquid" in "milliliters" we use "graduated cylinder". This represents the "volume of the water" or the "liquid". The "graduated cylinder" is labelled with the dimensions in the "milliliters". Measuring with "graduated cylinder" is some what difficult because of the "meniscus", this "meniscus" is the "curvature" of the surface of the water in the "graduated cylinder". The only problem is "meniscus" is attached to the edges of the cylinder but not in the middle of the cylinder. While looking at the cylinder the "meniscus" is not straight, hence the person should keep the "graduated cylinder" at his eye level.
A meander is best described as a bend or curve in a stream channel.
Answer:
199 g
Explanation:
Law of conservation of mass:
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
Explanation:
This law was given by french chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
For example:
In given reaction:
Reactant A = 115 g
Reactant B = 84 g
Product AB = ?
A + B → AB
115 g + 84 g = 199 g
199 g = 199 g
