Answer:
a. 916.95K is final temperature of the gas
b. 3667.8K
Explanation:
a. We can solve the temperature of a gas when the volume is expanded three times using Gay-Lussac's law:
P₁T₂ = P₂T₁
<em>Where P is pressure,</em>
<em>And T is absolute temperature of 1, initial states and 2, final states of the gas.</em>
<em />
Initial pressure is 6.60 atm, initial absolute temperature is 32.5°C + 273.15K = 305.65K. Final pressure is three times initial pressure = 6.60atm*3 = 19.8atm.
Solving for final temperature:
P₁T₂ = P₂T₁
6.60atm*T₂ = 19.8atm*305.65K
T₂ =
916.95K is final temperature of the gas

b. Charle's law is the gas law that relates changes in volume and temperature of a gas:
V₁T₂ = V₂*T₁
If the volume is quadrupled: V₂/V₁ = 4:
T₂ = 4*916.95K
T₂ = 3667.8K
In the gaseous state, the molecules are completely free because there is no intermolecular interaction between the molecules hence they translate at incredibly high velocity.
According to the kinetic theory of matter, the molecules that compose matter are in constant random motion. The nature of this motion varies in the three states of matter which are;
In the solid state, the molecules do not translate, they only vibrate and rotate about their mean positions. In the liquids state, the molecules translate but they still have restricted degrees of freedom due to intermolecular interactions. In the gaseous state, the molecules are completely free because there is no intermolecular interaction between the molecules hence they translate at incredibly high velocity.

Answer:
Please find the description below
Explanation:
The density of a substance refers to its mass per unit of its volume i.e the amount of a substance contained in a given volume. The density is calculated using the formula:
Density = mass/volume
Using this formula, with the known value for mass and volume of the boat, the density of the boat can be calculated.
An object will FLOAT on a liquid substance if its density is lower than that of the liquid while it will SINK if it has a higher density than that of the liquid.
In this case, with a known density of water, which is 1g/cm^3 or 1000kg/m^3,
a boat placed on water will FLOAT if its density is <1g/cm^3 (less than) while it will SINK if its density is >1g/cm^3 (greater than).
