Explanation:

Quantitative statement provide us information regarding the quantity which can be measured or can be written down in numeric form.

Qualitative statement provide us information regarding the quality or trat which cannot be measured.

1) Water has density of 1 g/ml.

Water is colorless in color.

2) Carbon has 6 electrons , 6 protons and  6 neutrons in it atom.

Carbon is an element which has black color and non metal.

3) Iron has boiling point of 2,862 °C.

Iron is a metal and good conductor of electricity.

4)Hydrogen gas has two hydrogen atom in its molecule

Hydrogen gas is a colorless gas.

5) Sucrose is an organic molecule made up of three different atoms

:carbon, oxygen, hydrogen.

Sucrose is termed as table sugar which tastes sweet to our tongue.

6) Table salt is compound made up of two atoms of sodium and chlorine.

Table salt is white in color.

7) Mercury has melting point of -38.83 °C

Mercury is liquid at room temperature.

8) Gold has an atomic mass of 198.97 g/mol.

Gold is shinny hard metal.

9) Air contains 78% of nitrogen , 21 % of oxygen and 1 % of other gases.

Air is a colorless mixture of gases which are the integral of the Earth planet.

A 48.0g sample of quartz, which has a specific heat capacity of 0.730·J·g−1°C−1, is dropped into an insulated container containi
Butoxors [25]

Answer:

The equilibrium temperature of the water is 26.7 °C

Explanation:

<u>Step 1:</u> Data given

Mass of the sample quartz = 48.0 grams

Specific heat capacity of the sample = 0.730 J/g°C

Initial temperature of the sample = 88.6°C

Mass of the water = 300.0 grams

Initial temperature = 25.0°C

Specific heat capacity of water = 4.184 J/g°C

<u>Step 2:</u> Calculate final temperature

Qlost = -Qgained

Qquartz = - Qwater

Q =m*c*ΔT

Q = m(quartz)*c(quartz)*ΔT(quartz) = -m(water) * c(water) * ΔT(water)

⇒ mass of the quartz = 48.0 grams

⇒ c(quartz) = the specific heat capacity of quartz = 0.730 J/g°C

⇒ ΔT(quartz) = The change of temperature of the sample = T2 -88.6 °C

⇒ mass of water = 300.0 grams

⇒c(water) = the specific heat capacity of water = 4.184 J/g°C

⇒ ΔT= (water) = the change in temperature of water = T2 - 25.0°C

48.0 * 0.730 * (T2-88.6) -300.0 * 4.184 *(T2 - 25.0)

35.04(T2-88.6) = -1255.2 (T2-25)

35.04T2 -3104.544 = -1255.2T2 + 31380

1290.24T2 = 34484.544

T2 = 26.7 °C

The equilibrium temperature of the water is 26.7 °C

What wave has the longer wavelength
natima [27]

The wavelength is the distance between one crest/trough to another crest/trough. On the image, it's basically the length between each peak of the wave. You can see that the distance between peaks in wave A are much shorter than the distance between the peaks in wave B.

Thus, wave B has the longer wavelength.
