Answer: Boyle's Law

Explanation:

Boyle's Law which is also called Mariotte's law was formulated by physicist Robert Boyle in 1662.

It posits that the pressure (p) of a given quantity of gas varies inversely with its volume (v) at constant temperature.

As the Scuba Diver went deeper, the volume of air dropped so the pressure increased.

In an electrochemical cell, electrons travel in which direction? * (a) from the anode to the cathode through the external circui
kompoz [17]

Answer:

(a) from the anode to the cathode through the external circuit

Explanation:

In an electrochemical cell, there are two half cells; the oxidation half cell and reduction half cell. Oxidation typically refers to loss of electrons and reduction refers to gain of electrons.

Electrons always flow from the anode to the cathode or from the oxidation half cell to the reduction half cell.

The electrical circuit in an electrochemical cell confirms the flow of electron. Usually a light bulb is attached. The correct option is;

(a) from the anode to the cathode through the external circuit

A student measures a cube composed of an unknown substance. The mass was determined to be 112.8 g, and the volume 63 cm3. What i
irina [24]

Answer:

D

Explanation:

The formula to find the density of an object is mass/volume. You know the mass in this problem is 112.8 grams, and the volume is 63 cm^3. Now you can plug this information into the density formula as 112.8/63, which is about 1.8. Now you just add the cm^3/g and you have your answer.

Assuming all other conditions remain the same, which of the following will cause an object's density to increase?
Elanso [62]

Taking into account the definition of density,  assuming all other conditions remain the same, increasing mass will cause an object's density to increase.

Density is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space. That is, density is a quantity referred to the amount of mass contained in a given volume.

Density is an intensive property since it does not vary with the amount of substance.

Since density is the relationship between the mass and the volume of a substance, its calculation is defined as the quotient between the mass of a body and the volume it occupies:

density=\frac{mass}{volume}

In the previous expression it can be observed that the density is inversely proportional to the volume: the smaller the volume occupied by a certain mass, the greater the density.

On the other hand, density is directly proportional to mass: the greater the mass, the greater the density.

Finally,  assuming all other conditions remain the same, increasing mass will cause an object's density to increase.
