Procedure number Procedure steps
1
Record the water temperature.
Put ice in the water.
Record the temperature after the ice melts.
2
Put ice in the water.
Touch the water to determine if it feels colder after the ice melts.
3
Measure the mass of water.
Put ice in the water.
Measure the mass of water when the ice cubes melt.
4
Determine the temperature and the mass of water.
Put ice in the water.
Note the melting time of the ice.

N, M, L
M, L, N 1: Temperature of sample 2 is higher
2: One drop 50 ml 10C one drop 50 ml 40C
3:1
4: M, L, N Surname is correct Gum, this is not cheating, we just need help from other students. 1: Temperature of sample 2 is higher
2: One drop 50 ml 10C one drop 50 ml 40C
3:1
4: M, L, N y’all r wack sum1 give me the answers🙏🙏🙏🙏🙏 The last name is correct… you made a good last name…..
-Bakugou Last name is 100% correct thank you very much 😘😘 that’s Bakugou’s way of saying thank you!!!
-kirishima Um hi guys um guess we are all cheating now… 0-0
– Izuku Midoriya For anyone like me who has different questions besides the first and others
1: The temperature of sample 2 is higher.
2: put a drop of food coloring in a cup with 50 ml of water at 10°C; place a drop of food coloring in a second cup with 50 mL of water at 40 ºC
3:1
4: M, L, N
Hope this helps, guess we all cheat now
-shoto totoroki Well, I feel like everyone gets an answer from here, why not?
Last name is correct ^^ – Uraraka Last name and law are correct!! And don’t think of it as cheating, just think of it as a little too useful homework help.
– Mina im a mha fan OwO Thanks for the help (Ribbit), hi guys too.
-Tsuyu Yes, I got 100% of the last name, there are so many anime fans… besides, the last name is correct. thank you last name <33 Yah last name Thank you brother! Also Hey guys!
– Denki what did I get into? Last name is correct
but like why are you rp on mha here i’m just trying to cheat 😭 Please help me Last name is 100% correct. I want dry noodles…. also Right is Right..
– Wang Liang Guys cheating is not acceptable in this class you know that…..but surname is correct oh lord @surname is correct for conexus students 2022
BAKUGOU OUT!! i love all anime fans here lol when people will learn this is not a rp site surname is correct!! thanks <33 The right is correct @the last name is correct. (: DIO!!!!!!!!!!!!!!! ORA ORA ORA ORA ORA ZUWARUDO Daniel what did you get??
A student adds ice to several water samples. The results are presented in the table. What conclusion can be drawn from the results? and the answers are this
When the temperature decreases, the kinetic energy of the sample increases.
When the temperature decreases, the kinetic energy of the sample increases.
As the amount of ice added decreases, the temperature decreases.
As the amount of ice added decreases, the temperature decreases.
As the amount of ice added increases, the temperature change increases.
As the amount of ice added increases, the temperature change increases.
When the temperature increases, the kinetic energy of water molecules decreases. Thank you, they are right HEY EVER! the last name is 100% correct, thank you!!!! right! is correct @YaMom’s Bae en 😭 do they Why r guys all say it’s cheating. Like brother… You are here too!
-J surname lysm thank you JOJO!!!! You thought it was me, but it was me, DIO! lol love how many jojo fans here What’s going on in the MHA? @Last name is correct for 2022 students conexus ty *ribbit* I got 100% thank you like <3 Oh wow I did NOT expect this to be flooded with a bunch of anime fans XD I love you all Annon, you are 100% right! ! :D bro I have totally different answers :( please help me bro- Quick check of potential and kinetic energy. :[ Carlos heats 2L of water on a burner. How can it measure the kinetic energy of water molecules? A. It can use litmus paper to measure the pH of water B. He can observe the movement of water molecules as they turn into water vapor C. He can use a scale to measure the mass of water D. It can use thermometer to measure water temperature my brain is not waking up so i need help ASAP! I have to pass Pikachuu~
PIKA!
(@surname, @Annon and @bon! are 100%) Bulba, Bulba
-Bublasaurus 2022 I AM HERE!
@The last name is correct but I didn’t expect future society heroes to be here
Young Midoriya, I am very disappointed in you my son. were like totally not cheating we just heard people giving us answers we need help with………we need help finding answers good guys i just wanted answers , not MHA fans🫥 @lastnameありがとうございます Thanks also to all anime fans. Where is Deku?
Why do we cheat?
-urakaka Urakaka, probably breaking his bones and somehow wrapping Bakugou, Todoroki or Iida in them. The surname is also correct.
– Jirou こんにちは爆豪ですが、本当に爆豪ですか？ T^T 私たちは決して知りません don’t cheat Kirishima! Wait… Are you cheating!?😡 I wish people wouldn’t cheat. I use this website to help teachers find the answer, not people give it to me.
