Answer:

B) line is the correct answer.

Explanation:

When light shines on a sample, each element emits specific wavelengths producing a unique fingerprint called its line spectra.

The line spectrum is electromagnetic spectra consist of discrete spectra lines.

When the atoms are excited they emit ray of specific wavelengths that correspond to various colors. The emitted ray can be seen as a range of colored line, this range of colored lines is termed as line spectra.

lines spectra are usually utilized to recognize atoms and molecules. Each element has individual line emission spectra.

How many 20.0-g ice cubes are required to absorb 47.0 kJ from a glass of water upon melting?
Sati [7]

Hello!


The number of 20-g ice cubes required to absorb 47 kJ from a glass of water upon melting is 7 icecubes


Why?


We are going to clear from the equation of the released heat, the mass of ice (m). The specific latent heat of fusion of ice is 336 kJ/kg:


Q=m*L\\ \\ m=\frac{Q}{L}=\frac{47 kJ}{336 kJ/kg}=0,1399 kg=139,88 g\\   \\ 139,88g*\frac{1 icecube}{20g}=6,99=7icecubes


So, 7 ice cubes are required to absorb that amount of heat from the glass of water.


Have a nice day!
