“Water” is the best thermal insulator.

Option: B

<u>Explanation</u>:

“Thermal insulators” are the materials which do not allow heat to transfer. “Water” is the substance which does not transfer heat. Hence, the “water” is the best “thermal insulator”. Water is the bad conductor of thermal heat. Water has “low thermal conductivity” than other substances, so this acts as an insulator as long as it is not traveled from one place to another. Heat is transferred when a “hot object collides” with “the cold objects”. The “thermal conductivity” of “water” is 0.6 W/m K.

How can endangered species be saved ?
labwork [276]

Answer:

There are lots of methods.

Explanation:

Usually, animals like pandas live a shorter lifespan in the wild than in captivity. A little fact, there is only one brown panda in the entire world, so it would be very, very rare to see one. The Smithsonian National Zoo, for example, are working to protect pandas, as well as other species.

Analyze the diagram showing the changing states of matter. Drag the item from the item bank to its corresponding match.
iVinArrow [24]

The correct matches for changes of state are:

  • 1 or 3 : Arrow that shows particles getting closer together
  • gas: State of matter that would fill any container
  • liquid: State of matter with definite volume but NOT shape
  • 2 or 4: Arrow that shows particles gaining energy
  • solid: State of matter with definite shape

<h3>What is change of state?</h3>

Change of state is the process whereby matter in one physical state is converted to matter in another state by the addition or removal of heat.

The process of change of state are:

  • Melting: solid to liquid due to addition of heat
  • Vaporization: liquid to gas due to addition of heat
  • Sublimation: solid to gas due to addition of heat
  • Freezing: liquid to solid due to removal of heat
  • Condensation: gas to liquid due to removal of heat
  • Deposition: gas to solid due to removal of heat

Considering the given diagram, the correct matches are:

  • 1 or 3 : Arrow that shows particles getting closer together
  • gas: State of matter that would fill any container
  • liquid: State of matter with definite volume but NOT shape
  • 2 or 4: Arrow that shows particles gaining energy
  • solid: State of matter with definite shape

In conclusion, change of state of matter occurs due to heat changes.

What volume would 56.2 mL of gas at 820 mm of Hg occupy at 720 mm of Hg?
Andreyy89

Answer:

49.35  mL

Explanation:

Given: 56.2 mL of gas

To find: volume that 56.2 mL of gas at 820 mm of Hg would occupy at 720 mm of Hg

Solution:

At 820 mm of Hg, volume of gas is 56.2 mL

At 1 mm of Hg, volume of gas is \frac{56.2}{820}

At 720 mm of Hg, volume of gas is \frac{56.2}{820}(720)=49.35\,\,mL
