Answer:

Subatomic particles making up an atom

Explanation:

Atom is the smallest unit of any matter

An atom consists of three subatomic particles - Protons, Neutrons, Electrons. Major atomic mass is in the nucleus ie a tiny deep area at the centre. Nucleus consists nucleons, which includes protons (positively charge) & neurons (neutrally charged). Negatively charged electrons are outside the central nucleus.

Boyle's law states that the pressure of a gas is always:

natka813 [3]

Answer:

d. inversely proportional to the volume of its container.

Explanation:

Boyle's law states that at constant temperature and number of moles, the pressure of the gas is inversely proportional to the volume of the gas.

Thus, P ∝ T

P is the pressure

T is the temperature

For two gases at same temperature, the law can be written as:-

${P_1}\times {V_1}={P_2}\times {V_2}$

<u>Thus, according to the question, the answer is:- d. inversely proportional to the volume of its container.</u>

Which activity might help to increase the validity of this experiment?

MArishka [77]

A should be the answer because the more you test an experiment the more data you have to rely on changing the experiment would cause you to have different outcomes making the results different and unreliable so B, C, and D is not going to be the answer Hope this helps

Boyles Law P1V1 = P2V2

arsen [322]

Answer:

A. The balloons will increase to twice their original volume.

Explanation:

Boyle's law states that the pressure exerted on a gas is inversely proportional to the volume occupied by the gas at constant temperature. That is:

P ∝ 1/V

P = k/V

PV = k (constant)

P = pressure, V = volume.

$P_1V_1=P_2V_2$

Let the initial pressure of the balloon be P, i.e. $P_1=P$ , initial volume be V, i.e. $V_1=V$ . The pressure is then halved, i.e. $P_2=\frac{P}{2}$

$P_1V_1=P_2V_2\\\\P*V=\frac{P}{2} *V_2\\\\V_2=\frac{2*P*V}{P}\\\\V_2=2V$

Therefore the balloon volume will increase to twice their original volume.

What is the energy conversion that occurs in cellular respiration?

fomenos

Cellular respiration is the process by which the chemicalenergy of "food" molecules is released and partially captured in the form of ATP. Carbohydrates, fats, and proteins can all be used as fuels in cellular respiration, but glucose is most commonly used as an example to examine the reactions and pathways involved.
