Answer:



Explanation:
Given:
- volume of liquid content in the can,

- mass of filled can,

- weight of empty can,

<u>So, mass of the empty can:</u>



<u>Hence the mass of liquid(soda):</u>



<u>Therefore the density of liquid soda:</u>
(as density is given as mass per unit volume of the substance)


<u>Specific weight of the liquid soda:</u>



Specific gravity is the density of the substance to the density of water:

where:
density of water

Answer:
Yes convection will always work faster and more efficiently.
Explanation:
When a gas or a liquid is heated, hot areas of the material flow and mix with the cool areas. ... Convection transfers heat over a distance faster than conduction. But ultimately conduction must transfer the heat from the gas to the other object, though molecular contact.
160w/4 = 40w
1000J/ 4= 250J
a 40w light bulb will consume 250J
