the resistance of ______ will decrease when it is heated

a)constantan
b)thermistor
c)tungsten
d)iron

lordkvng:
physics peeps only

on what principle does pressure cooker work ?

Happy Sunday

clintonopah:
the heat loss is being regulated... so the pressure is high and constant....causing decrease in boiling point

clintonopah:
1 raise or fall in capillary tube
2 concave meniscus
3 the force of adhesion is stronger than cohesion
4 convex meniscus
5 principle is used in umbrella
6 the force that exist in a liquid
7 oil- grease- ice

hmmm.
how does increase in pressure decreases boiling point pls explain.

does it mean that ..increasing from 100 to 120 won't. make it boil longer clarify me please

ice isn't a liquid na...lemme help u.turpentine is

Errrrr... I just wanna say something. If you're using your textbook or google to answer the questions posted here, *chuckles* you're on your own ooo... On that day, google, textbook, even calculator nor go dey.

medwhite0:
thermistor i think. because it is formed from semi conductors

lordkvng:

water is also viscous.. in fact all liquids are viscous, just some r more viscous than others.

clintonopah:
what is relegation

lordkvng:

relegation can otherwise be refreezing of ice.. according to the experiment, a thin wire can pass through ice without it(ice) breaking

lordkvng:
at a high altitude a liquid _____
a)the boiling point of water is less than 100 b)the boiling point of water is more than 100 c)the boiling point is equal to 100 d)the boiling point is 4degrees.
