Campers want a travel cup that keeps the temperature of a beverage from changing for up to two hours.
They may want to keep a hot drink hot when they are in a cold place. Or they may want to keep a cold drink

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.

what is the difference between quantative and qualitative analysis​

Answers

Answer:

Quantitative data can be counted, measured, and expressed using numbers.  Qualitative data is descriptive and conceptual.  Qualitative data can be categorized based on traits and characteristics.

Explanation:

Quantitative analysis involves looking at the hard data, the actual numbers. Qualitative analysis is less tangible. It concerns subjective characteristics and opinions – things that cannot be expressed as a number.

if 5 L of butane is reacted what volume of carbon dioxide is produced ILL GIVE BRAINLIEST

Answers

Answer: First, here is the balanced reaction:  2C4H10  +  13O2  ===>  8CO2  +  10H2O.

This says for every mole of butane burned 4 moles of CO2 are produced, in other words a 2:1 ratio.

Next, let's determine how many moles of butane are burned.  This is obtained by

5.50 g / 58.1 g/mole  =  0.0947 moles butane.  As CO2 is produced in a 2:1 ratio, the # moles of CO2 produced is 2 x 0.0947  =  0.1894 moles CO2.

Now we need to figure out the volume.  This depends on the temperature and pressure of the CO2 which is not given, so we will assume standard conditions:  273 K and 1 atmosphere.

We now use the ideal gas law PV = nRT, or V =nRT/P, where n is the # of moles of CO2, T the absolute temperature, R the gas constant (0.082 L-atm/mole degree), and P the pressure in atmospheres ( 1 atm).

V = 0.1894 x 0.082 x 273.0 / 1  =  4.24 Liters.

What is an Electron ?

Electron is a subatomic particle (denoted by the symbol e⁻)

or  whose electric charge is negative one elementary charge.

Electrons belong to the first generation of the lepton particle family and are generally thought to be elementary particles because they have no known components or substructure.

The electron has a mass that is approximately 1/1836 that of the proton.

Ni(s) + 2HCl(aq) - NiCl(aq) + H₂(g)

This is an oxidation-reduction (redox) reaction:

2 H⁺ + 2 e⁻ → 2 H (reduction)

Ni - 2 e⁻ → Ni ²⁺ (oxidation)

HCl is an oxidizing agent, Ni is a reducing agent.

Therefore Ni Atom loses 2 electrons , Option 2 is the correct answer.

What is the volume, in L, of 2.50 moles of oxygen gas measured at 25.0oC and a pressure of 104.5 kPa?

Answers

Answer:

58.53 L

Explanation:

Ideal gas equation is

PV = nRT

P - the pressure of the gas = 104.5  KPa

V- the volume occupied by the gas

n  - the number of moles of gas =2.50

R - the universal gas constant, usually given as  0.0821 atm.L/(mol K)

T - the absolute temperature of the gas.= 298K

[tex]V =\frac{nRT}{P}[/tex]

Now substituting vales we get

[tex]V = \frac{2.5\times0.0821\times298}{104.5\times1000}[/tex]

V = 58.53 L

What is the new pressure if the temperature outside is 296k and his weight causes the tire's volume to drop to 2.0 liters

Answers

Question:

At standard temperature and pressure, the volume of a tire is 3.5L. What is the new pressure if the temperature outside is 296k and its weight causes the volume of the gas is 2.0 L?

Answer:

The new pressure is: 1.896 atm

Explanation:

At standard temperature and pressure, we have:

[tex]P_1 = 1atm[/tex]

[tex]T_1 = 273.15k[/tex]

[tex]V_1 = 3.5L[/tex]

Outside, we have:

[tex]T_2 = 296k[/tex]

[tex]V_2 = 2.0L[/tex]

Required

Determine the new pressure

Using combined gas law, we have:

[tex]\frac{P_1V_1}{T_1} =\frac{P_2V_2}{T_2}[/tex]

This gives:

[tex]\frac{1 * 3.5}{273.15} =\frac{P_2*2.0}{296}[/tex]

Solve for [tex]P_2[/tex]

[tex]P_2 = \frac{296 * 1 * 3.5}{273.15*2.0}[/tex]

[tex]P_2 = \frac{1036}{546.30}[/tex]

[tex]P_2 \approx 1.896 atm[/tex]
