A solid and hollow metallic spheres made of same material ond having same volume are heated upto same temperature
range. Why solid sphere takes more amount of heat?

frequency or wavelenth of em radiation in a vacuum

graph slopes whilst gas cools, then it is flat whilst conensation to liquid happens, the coolong liquid then graphs as a slope when it solidifies graph is flat

latent heat

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
