Help please ! Fill in the blank with the letter of the term that best matches the situation.

Matching Terms:
A Variables
BAnalysis
C. Experimental group (warmer or colder than body temperature)
D Conclusion
E Data collected
F. Controlled conditions
G. Preliminary observation
H. Control closest to body temperature) I .Hypothesis
J. Question

22. Materials feel warm or cool tot not touch

23 Wood

24 Metal, styrofoam

25 Will different surfaces affect the melting rate of and ice cube

26 Different counter surfaces

27 if an ice cube is placed on the surface of each material then the material that's feels warmest will melt the ice cube the fastest.

28 Measurement of melting time

29 the material that felt the coolest melted the ice the fastest

30 same sized ice cubes flat surfasted materials and equal mass

31 the materials tested were at room temperature since body temperature was warmer than room temperature heat will be lost to the material and direct relationship to its density styrofoam at least you're still closer to the body temperature and didn't lose much however it was the best insulator and maintained the ice the longest.

THANK YOU ! ​​

Which statement about covalent bonds is true

The passing of heat through a material while the material itself stays in place. a. radiation b. conduction c. convection

Aplane flies a distance d from west to east at a constant speed vp , with respect to the air in a time twe . on the return trip, the plane flies a distance d from east to west at a constant speed vp , with respect to the air in a time tew . on both trips the wind blows from west to east at a constant speed va , with respect to the ground 1) what is tew in terms of vp, va, and d, as needed? tew=dvp tew=dvp+va tew=dva tew=dvpâ’va tew=12dvp tew=12dvp+va tew=12dvpâ’va your submissions: b submitted: saturday, january 26 at 6: 49 pm feedback: feedback will be given once all questions have been attempted and the grade cluster button has been pressed. 2) what is twe in terms of vp, va, and d, as needed? twe=dvp twe=dvp+va twe=dva twe=dvpâ’va twe=12dvp twe=12dvp+va twe=12dvpâ’va your submissions: d submitted: saturday, january 26 at 6: 49 pm feedback: feedback will be given once all questions have been attempted and the grade cluster button has been pressed. 3) assuming d = 2300 miles, vp = 400 miles/hr, and twe = 4 hours, what is va, the speed of the wind with respect to the ground? va = 100 miles/hr va = 575 miles/hr va = 200 miles/hr va = 175 miles/hr va = 975 miles/hr 4) once again, assuming d = 2300 miles, vp = 400 miles/hr, and twe = 4 hours, what is tew, the time it takes the plane to fly a distance d miles from east to west? tew = 5.75 hours tew = 11.5 hours tew = 7.67 hours tew = 8 hours tew = 10.2 hours
