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 !

Atwo-stage air compressor operates at steady state, compression 10m^3/min of air from 100 kpa and 300k to 1200 kpa. an intercooler between the two stages cools the air to 300k at a constant pressure of 350 kpa. the compression processes are isentropic. a) calculate the power required to run the compressor, in kw b) compare the result to the power required for isentropic compression from the same inlet state to the same final pressure.

Determine the change in width a, height b, thickness t when a plate is subjected to the uniform distributed load and is made of material having modulus of elasticity e=230 gpa and poisson's ratio ν=1/3. given : a=400 mm and b= 300 mm also the uniformly distributed load in downward y direction of plate is 2 mn/m and in the positive x direction is 3 mn/m and t=20 mm
