<span>So the question is how can a spoon sound like a bell. Sound waves are mechanical waves that have their frequency. When a source, in this case a spoon and a bell oscilate, they produce sound waves. If they produce those sound waves in the same frequency, then we can say they produce the same tone thus they sound the same.</span>

Heat the solution, dissolve the solute, and let it cool verifying nothing settled out.
Explanation:
Using the Gay Lussac's Pressure Temperature Law :
P1/T1 = P2/T2
Substituting the values:
Let x be the new gauge pressure.
40/60 = x/90
x = 60 psi.
T<span>he gauge pressure will be 60 psi when the soda reaches 90oF.</span>
Answer:
When the thermometer is warmed, the liquid expands by more than the volume of the hollow space in which it is confined, and so some of it must move from the bulb into the capillary tube. It should be conduction and then convection/advection, not radiation. Radiation is usually the slowest heat transfer.
