Describe how you plan to design, build, and test a travel cup that uses thermal insulators?

Answers

The statement is "thermal insulators of a double-layered vacuum seal make a liquid heated when it's cold and keep it cool when it's hot."

What is thermal insulator?

A thermal insulator is a material that inhibits heat from being conveyed from one location to another.

Campers seek a travel cup that cools liquids with a cold pack. Design the exterior portion of the cup to keep the drink cold after it has cooled down, as well as the interior compartment to contain the cold pack and channel heat from the liquid in the cup. One of the greatest ways to keep your coffee hot for a long time is to use vacuum insulation in a thermos. On the surface, the concept appears straightforward.

why don't we ever see solid or liquid oxygen on earth?

Answers

Please mark me brainiest!

The reason why you don’t see solid or liquid oxygen is because oxygen is a natural occurring gas. Gas can not be solid or liquid because there is too much energy to have volume/shape. That’s why you see oxygen tanks, as the tank keeps the gas contained and that is why you can’t see it in the air outside or in something like H20 (water).

State two methods to increase the rate of the chemical reaction and explain
for each, in terms of particle behavior, how each method would increase
reaction rate.
METHOD 1:
Explanation:
METHOD 2:
Explanation:

Answers

Answer:

METHOD 1: (surface area of a solid reactant) METHOD 2: (concentration or pressure of a reactant)

Explanation:

METHOD 1: (surface area of a solid reactant) Increasing the surface area of a solid reactant exposes more of its particles to attack. This results in an increased chance of collisions between reactant particles, so there are more collisions in any given time and the rate of reaction increases.

METHOD 2: (concentration or pressure of a reactant) Increasing the concentration means that we have more particles in the same volume of solution. This increases the chance of collisions between reactant particles, resulting in more collisions in any given time and a faster reaction. As we increase the pressure of reacting gases, we increase the rate of reaction.
