1)can't see the illustration 
2) -2+10=8  and-4+12=8
3) 123-180= -57  185-255=-70
Bart has -57 points and Sam has -70 points  which means that  Bart won the game because after adding up the sums  their games Bart has a total of -57 and Sam has a total of -70  and -57 is higher then -70.

Drag each tile to the correct box.

The amount of heat depends on three factors:-

#Mass of the material used in bowls.

#Specific heat capacity of the material used in bowls.

#Temperature change.

So, (change in energy) = (mass) x (specific heat capacity) x (temperature change)

Temperature Change = (Change in energy) / (mass x specific heat capacity)

It says "The bowls start at the same temperature, and then the same amount of heat is added to each bowl". It means temperature change varies inversely with product of mass and specific heat capacity.

Higher the product of mass and specific heat capacity, Lower the temperature change, Cooler the bowl will be.

Water’s specific heat capacity is 4.186 joules/gram degree Celsius. Mercury’s specific heat capacity is 0.140 joules/gram degree Celsius.

Water and mercury are put into three identical bowls:

#Bowl A contains 20 grams of water.

#Bowl B contains 40 grams of water.

#Bowl C contains 20 grams of mercury.

So, we have (40g x 4.186 J/g) > (20g x 4.186 J/g) > (20g x 0.140 J/g)

It means temperature change in <u>Bowl B < Bowl A < Bowl C.</u>

<u>Hence, Order of the bowls from coolest to warmest, based on their final temperatures would be</u><u> Bowl B < Bowl A < Bowl C.</u>
