Answer 5

salt?,

Answer 6

What investigation did you do?

Answer 7

Yea, it's salt

Answer 8

Can you explain the process

Answer 9

why salt

Answer 10

salt water has a lower freezing temperature than pure water ,

adding salt to the snow, makes it melt

Answer 11

The main idea is that salt lowers melting and freezing point
and it melts ice faster but...

Answer 12

when salt was added on a beaker containing ice, the thermometer reading decreases. Why

Answer 13

this works because it takes energy to keep the salt ions moving in the solution

Answer 14

when ice melts, temperature increases rite

Answer 15

@UnkleRhaukus

Answer 16

the energy required to melt a solid - goes to kinetic energy of the molecules, and does not increase the temperature, only when all the solid is completely melted does extra energy go to increasing the temperature

Answer 17

So, when salt is added, ice starts to melt and temperature maintains or decreases ?

Answer 18

as you found, the temperature decreases, thermal energy of the thermometer/etc is used to melt the ice

Answer 19

thermal energy of the thermometer

Answer 20

Can you explain this

Answer 21

the thermometer cools to the temperature of the salt water solution

Answer 22

Thanks @UnkleRhaukus
