What is the average amount of energy of motion in the particles of a substances?
Temperature.
Why same amount of heat supplied to same amount of different substances does not produce the same increase in temperature?
There is a formula in physics ΔQ=m*c*ΔT, where m is the mass of the substance you are heating, ΔQ is the heat you supply to the substance, c is the specific heat which has a different value for different substances and ΔT is the change in temperature. If your substances are different and they have the same mass then by supplying the same amount of heat the change in temperature will be different.
How does density depend on the amount of material?
Because density is an intensive property, it does not depend on the amount of material. Density is a ratio between mass and volume, D=M/V. That specific ratio is constant for any material. For example, the smallest sample of aluminum and the largest sample of aluminum have a density of 2.70 g/cm^3 at room temperature. Density does change with temperature because temperature affects volume. The density of all samples of aluminum at its melting point is 2.375 g/cm^3.https://en.wikipedia.org/wiki/Aluminium
How much weight can aluminum hold?
There is effectively no limit to the amount of weight that aluminum can hold, if you use enough aluminum.
What is the minimum amount of energy required for two substances to react?
The minimum amount of energy needed is called the "activiation energy". It varries depending on factors such as your reaction, temperature and several others.
Does temperature depend on the amount of a substances?
The answer is no
Does temperature depends on the amount of substances?
actually no it doesnt
What is the average amount of energy of motion in the particles of a substances?
Temperature.
What will happen if aluminum is mixed with copper?
If a mixture of the right amount of aluminum and copper is lit on fire at a high enough temperature then it can produce Thermite, which burns at an extremely high temperature.
What is the amount of dissolved salts in a substances?
This is called the solubility at a given temperature and pressure.
Which would have higher temperature change water or aluminum?
Starting from the same temperature and for the same amount of heat input, aluminum would wind up with a higher temperature than water because water has a higher heat capacity (it takes more energy to raise its temperature) than aluminum.
How can we extract metal from bauxite ore?
Extracting aluminum from bauxite ore requires a large amount of electricity.
What is substances specific heat?
The amount of heat required to increase the temperature of the substance to 1 degree greater than that of the initial temperature of the body!
Why same amount of heat supplied to same amount of different substances does not produce the same increase in temperature?
There is a formula in physics ΔQ=m*c*ΔT, where m is the mass of the substance you are heating, ΔQ is the heat you supply to the substance, c is the specific heat which has a different value for different substances and ΔT is the change in temperature. If your substances are different and they have the same mass then by supplying the same amount of heat the change in temperature will be different.
What is the substances specific heat?
The amount of heat required to increase the temperature of the substance to 1 degree greater than that of the initial temperature of the body!
What are 4 things that affect the rate of a reaction?
1. The concentration of the substances. 2. The temperature. 3. The surface area of the particles. 4.The presence of a catalyst.
Why do substances with large heat capacities make good heat storing substances?
Because of large heat capacities temperature rise will be very low so large amount of heat can be stored.
