Question

please help!!!!

Materials needed

2 glass jars or beakers that will hold at least 1/2 cup of water
- 2 sugar cubes
-ice water straight from the refridgerator
- hot water from the tap
- a kitchen measuring cup
- a stopwatch

procedure:
1.using the measuring cup to measure 1/2 cup of ice water. pour the water into one of the glass jars.
2. plave one sugar cube in the jar of water.
3.begin stirring the water with the sugar cube without stabbing the sugar cube.
4.record the time it takes for the sugar cube to completley disolve.
5. Now repeat steps 1 through 4 but this time use ho

Answer 1

the hot water( wait until you are ready to do this step to take the hot water from the tap so that it will be hot as possible when you begin this step.

all i need is someone to tell me the

hypothesis
observation/data
discussion of resault
please medals deff rewarded I really need your help!

Answer 2

well the hypothesis you need to do that your self just put down what will happen after you do ever thing above

Answer 3

i dont have sugar cubes:( perhaps you can help?

Answer 4

nor do i have sugar right now

Answer 5

your observation/data is how long it will take the sugar cube to melt

Answer 6

so wat do you think would be a good observation?

Answer 7

ok so for hypothesis really fast what do you think will melt fast the sugar cube in cold or warm water and this does not have to be right at all

Answer 8

you think of that and i will be right back

Answer 9

I think that the sugar cubes will melt faster in warm water:)

Answer 10

ok so put that as our hypothesis

Answer 11

The solubility will be higher in hot water, because the heat will increase the kinetic energy of the particles and help them dissolve more easily.

Answer 12

is this good?

Answer 13

now the last 2 things i cant do cause i also do not have sugar but i can tell you what to do for your data just put the sugar in cold and warm water and then just right down which one melts first and how long it took then for the last thing the discussion of resault just put down i was right the warm water did make the sugar melt faster but if you did not get it right then put i was wrong the sugar melted in cold water faster and thats all you do

Answer 14

alrighty thankyou so much for your help yer really nice!

Answer 15

Yea np

Answer 16

is this a good observation:)

using the hot and cold water I found that hot water disolves more sugar than cold water, because hot water expands, so their is more space between the molecules in hot water than cold?

Answer 17

yea perfect

Answer 18

im stuck on the resault part it wants me to explain my resaults and discuss the probable reasons for your observation

Answer 19
