A block of wood has a volume of 125 cm has a mass of 27 g. What is the density of this block ?

Answers

Answer:

27/125

(3/5)³

(0.6)³

0.216 gm/cm³ or g/cc

Explanation:

Given:
Volume = 125 cm³
mass: 27 grams

Here Density is actually the amount of matter present in unit volume.

Mathematically, rho(like p) (tapering downwards) = Mass/Volume
Putting, 27/125 g/cm³

0.216 g/cc

Explain why water boiling in a container stops
boiling momentarily when the lid is removed

Answers

Answer:

It's because it tips over the threshold from nucleate boiling, which we can see, to convection boiling, which we can't. ... Even if the steam stayed in the pot, it would still stop boiling when you removed the heat. The steam and water in a liquid/vapour mixture are at the same temperature (100ºC).
