Is there a relationship between CO2 levels in average global temperatures

Chemistry
1 answer:
Vilka [71]2 years ago
8 0

Answer:

Yes

Explanation:

A small part of the correspondence is due to the relationship between temperature and the solubility of carbon dioxide in the surface ocean, but the majority of the correspondence is consistent with a feedback between carbon dioxide and climate.

Substance A has the following properties.
ella [17]

It will take 1.11 min to heat the sample to its melting point.

Melting point = - 20°C

Boiling point = 85°C

∆H of fusion = 180 J/g

∆H of vap = 500 J/g

C(solid) = 1.0 J/g °C

C(liquid) = 2.5 J/g °C

C(gas) = 0.5 J/g °C

Mass of sample = 25 g

Initial temperature = - 40°C

Final temperature = 100°C

Rate of heating = 450 J/min

Specific heat capacity formula:- q = m ×C×∆T

Here, q = heat energy

        m = mass

        C = specific heat

      ∆T = temperature change

Melting point = - 20°C

C(solid) = 1.0 J/g °C

∆T = final temperature - initial temperature = -20 - (-40) = 20

Put these value in  Specific heat capacity formula

q = m ×C×∆T

q = 25×1.0×20

   =500J

The Rate of heating = 450 J/min

i.e. 450J = 1min

so, 500J = 1.11min

1.11 minutes does it take to heat the sample to its melting point.

The specific heat capacity is defined as the amount of heat absorbed in line with unit mass of the material whilst its temperature increases 1 °C.

Describe the nucleus of the<br> atom.
miskamm [114]

Answer:

The nucleus of atom is composed of two subatomic particles that each have charges.

  • Protons, which are positively charged particles.
  • Neutrons, which are neutrally charged particles.

Both reside in the nucleus of an atom. The amount of protons and neutrons (Electrons can to) is what helps us identify each atom apart. Electrons are NOT in the nucleus of atom but orbit it in outer layers called orbitals.
