Answer:

it goes to a solid to a liquid

Explanation:

When something is a solid the molecules are impact together and have a small sense of vibration. But as the solid melts away for example ice, the molecules become more loose forming into a liquid

A gas occupies a volume of 0.2 L at 176 mm Hg. What volume will the gas occupy at 760 mm Hg?
nignag [31]

Answer:

V_2=0.046L

Explanation:

Hello,

In this case, we apply the Boyle's law as an inversely proportional relationship allowing us to understand the pressure-volume behavior as shown below:

P_1V_1=P_2V_2

In such a way, solving for the final volume V2, we obtain:

V_2=\frac{P_1V_1}{P_2}=\frac{0.2L*176mmHg}{760mmHg}  \\\\V_2=0.046L

Best regards.

What is the volume of a gas a t320 K, if the gas occupies 50.0 mL at a temperature of 273 K?
shtirl [24]

Answer:

58.61mL

Explanation:

V1 (initial volume) =?

T1 (initial temperature) = 320 K

V2 (final volume) = 50mL

T2 (final temperature) = 273 K

Using the Charles' law equation V1/T1 = V2/T2

The initial volume of the gas can obtained as follow:

V1/320 = 50/273

Cross multiply to express in linear form

V1 x 273 = 320 x 50

Divide both side by 273

V1 = (320 x 50)/273

V1 = 58.61mL

Therefore, the initial volume of the gas is 58.61mL

How does the city filter our drinking water?
pantera1 [17]
Water purification is the process of removing undesirable chemicals, biological contaminants, suspended solids and gases from contaminated water. The goal is to produce water fit for a specific purpose. Most water is disinfected for human consumption (drinking water), but water purification may also be designed for a variety of other purposes, including fulfilling the requirements of medical, pharmacological, chemical and industrial applications. The methods used include physical processes such as filtration, sedimentation, and distillation; biological processes such as slow sand filters or biologically active carbon; chemical processes such as flocculation and chlorination  and the use of electromagnetic radiation such as ultra violet light.
