Will a solid form of a substance react faster or slower than a powdered form?
Slower
Substance A has a higher heat capacity than does substance B and substance B has a higher heat capacity than does substance C. If you add the same amount of heat to all three which order shows the pro?
c
Why is it necessary to use a powder rather than a crystalline sample when determining melting point?
with a crystalline solids ,transfer of heat will not be uniform which can cause an error in the determination of the melting point of a substance .
Why does water evaporate slower than rubbing alcohol?
Water evaporates slower than rubbing alcohol because it is a more stable substance. The bonds in water are very strong.
If a substance has a specific heat less than one would it take more or less heat to raise the temperature?
The higher the substance's specific heat capacity, the more heat energy is needed to raise it's temperature.
What does It mean when one substance is known to be better conductor of heat than another?
It has more free electrons in the outer energy band.

As heat flows into substance will the atoms of that substance move faster or slower?
Yes. Atoms move faster in hot water because by increasing the heat, you are increasing the thermal energy. The higher the heat, the faster the atoms move. Blow up a balloon into the shape of an egg and attach it to a small weight so it sinks. Place the balloon in a glass with cold water and ice. See what happens to the balloon. Then, take the balloon and place it in a warm cup of water. The balloon will expand again, and that is because the atoms are going "nuts" and jumping around! That is kinetic energy!
Does water heat up faster or does land?
water warms up slower than land. It also loses heat slower.
What is it called when the sand is hotter than the water?
Water has a higher specific heat than the land. This means that the surface of the water will heat up slower and cool down slower than the land.

Is heat slower than sound in air?
Heat being transferred in three modes. They are conduction, convection and radiation As far as conduction and convection are concerned they may be slower than sound But radiation is by electromagnetic wave. It has the speed of light. So it is not slower than sound.
What is Heat transfer in high speed flow?
It is heat transfer at speed higher than 0.3 Mach.
Will wood keep ice cold?
Wood has characteristics of an insulator. Every material, such as glass, steel, rubber or cotton, will either have characteristics that either allows it to transfer Heat or to restrict heat. This is its heat transfer characteristic. Every material will transfer Heat in various rates. So if you place ICE in a box made of ice, it will melt slower than if the ice is left out by itself. The wood slows the outside heat from getting to the ice and causing it to melt.
Why is it necessary to use a powder rather than a crystalline sample when determining melting point?
with a crystalline solids ,transfer of heat will not be uniform which can cause an error in the determination of the melting point of a substance .
Is ddr2 slower than ddr3?
DDR2 is slower than DDR3 due to their difference in bandwidth. DDR3 has a higher bandwidth hence can transfer data at higher speeds than DDR2.
Why velocity of sound is slower than normal in winter?
cause the air has less heat(energy) and will vibrate slower.
