I NEED HELP PLEASE. THIS IS A PROJECT SO PLEASE TRY AND ANSWER CORRECTLY. WILL MARK BRAINLIEST AND GIVE GOOD RATING Down below I attached a picture of the data I recorded during the virtual experiment. Basically its an experiment on how good different material cloths wrapped around a coffee cup insulates the warm water on the inside.

Here are questions to help you answer the question (THESE QUESTIONS ARE ONLY NEEDED TO HELP SOLVE FOR THE ANSWER NO NEED TO SEND THEM THROUGH ON HERE)

1.) Calculate the change in temperature from start to finish for the air and each of the samples and record on your data sheet.
2.)Which water sample lost the least amount of heat energy over the 6-minute time interval?
3.)Was the rate of heat loss constant during each experiment? How can you tell?
4.)Which material was the best insulator? Which material was the least effective insulator?

Write a summary paragraph discussing this experiment and the results. Use the following questions and topics to help guide the content of your paragraph.

1. ) According to your data, was your hypothesis correct? (Be sure to refer to your data and graphs when answering this question.)

2.) Summarize the conclusions that you can draw from this experiment. Use the questions above to guide your ideas.

3.) Summarize any difficulties or problems you had in performing the experiment that might have affected the results. Describe how you might change the procedure to avoid these problems.

Those are the only 3 questions i need answered ^^
