Explain why a fluorescent light bulb is not as hot
as an incandescent light bulb.

Fluorescent tubes do not get as hot as incandescent bulbs because they emit most of their energy as light. This means that they use energy very efficiently. One 18-watt fluorescent tube provides the same amount of light as a 75-watt incandescent bulb, and the fluorescent tube lasts ten times longer.

Explanation:

You can write about anything as long as you include at least one of these things

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
