Answer:

physical or chemical

Explanation:

A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance while a chemical property describes the ability of a substance to undergo a specific chemical change.

Air pressure keeps liquid molecules from escaping as a gas, affect the boiling point of a liquid. Therefore, option B is correct.

A liquid's boiling point changes depending on the pressure being applied; the normal boiling point is the temperature at which the vapour pressure is equal to the average atmospheric pressure at sea level (760 mm [29.92 inches] of mercury). Water boils at sea level at 100° C (212° F).

The boiling point of a liquid is influenced by the pressure of gas above it. This is referred to as atmospheric pressure in an open system. The higher the boiling point and the more energy is needed to bring liquids to a boil, the higher the pressure.

Thus, option B is correct.

Answer:

1. Nonmetal

2. Nonmetal

3. Covalent

Explanation:

CH4 is the chemical formula for the methane molecule in which four atoms of hydrogen is chemically bonded to one atom of carbon. Both carbon, which is the first element and hydrogen the second element are non-metals, and hence can only form a covalent bond.

A covalent bond is a type of chemical bond in which two atoms share their valence electrons. It occurs between two non metallic atoms. In this molecule, CH4, carbon and hydrogen share their valence electrons to form a covalent bond.

Answer:

is B

Explanation:

it isnt C or D so let's look at A and B so the answer is more likely going to be B because A your muscles cant change shape and C your muscles are protien and D humans and animals do not have cell walls that only have cell membrane

Answer:

No B. is incorrect, the REAL answer is actually C.

Explanation:

The main function of muscles is to move body parts by contracting, which requires a lot of energy. so C. is the only answer that concludes with this. The cell structure that produces energy is the mitochondrion.

Therefore, the best prediction is that muscle cells contain a large number of mitochondria in order to provide more energy.

So that means B. would be an assumable answer.

3)The formula for speed is

speed=distance ÷ time

distance is in metres (m)

and time is in seconds (s),

so the units will be in metres per second (m/s).

4)to solve for distance use the formula for distance d = st, or distance equals speed times time. ... You can use the equivalent formula d = rt which means distance equals rate times time. distance = rate x time.

5)To solve for time use the formula for time,

t = d/s which means time equals distance divided by speed.

6)The SI unit of speed is the metre per second, but the most common unit of speed in everyday usage is the kilometre per hour.

Answer:

Flow rate is how fast a fluid moves. The flow rate can depend on several factors. These factors are the type of fluid that you are using, the force that is pushing on a fluid, the size of the pipe the fluid flows from and the type of surface the fluid flows over. Viscosity is the resistance of a fluid to flow.
