How do you increase the pressure of gas?
decreasing the volume available for the gas or increasing its temperature
Which item requires the least energy to increase its temperature lounge chair sand or water Explain your answer in terms of this item's specific heat?
Sand needs least energy to increase the temperature as its specific heat is very low compared to that of water. Water needs more energy to increase its temperature as its specific heat capacity is higher.
What is the relationship between the density and the specific heat capacity of a pure substance?
Density is directly proportional to the specific heat.
Does temperature of a gas increase or decrease under pressure?
If a gas is pressurised then the temperature will increase.
Does temperature increase with increase in velocity?
no it doesnt
Which of the following does not increase the rate of dissolving a solid in water?
- a decrease in temperature - an increase of the particles dimensions - lack of stirring
Which of the following increase with depth within Earth's interior?
Temperature
How do you increase the pressure of gas?
decreasing the volume available for the gas or increasing its temperature
Would substances with high specific heat capacity also have high temperatures?
Specific heat capacity is the amount of energy or heat required to raise the temperature of a unit mass of a substance by one kelvin. So if the specific heat capacity is high then you would require more energy or heat to raise its temperature. The specific heat capacity does not really have anything to do with how much you can increase an objects temperature. IT HAS TO DO WITH THE ENERGY NEEDED TO INCREASE THE TEMPERATURE.
How does temperature affect the physical properties of petrol?
An increase in temperature will reduce the density, reduce the viscosity, reduce thermal conductivity, and increase the specific heat capacity. A decrease in temperature will have the opposite affect.
How do you Increase solubility of liquid in liquid?
Increase temperature. any of the following:- 1) increase the temperature of the Solvent (what you are trying to dissolve in) 2) increase the surface area of the Solute (what you are dissolving) 3) increase the agitation (stirring) and the amount of the solvent.
Which of the following tends to increase the rate of a chemical reaction?
Increasing the temperature of the reactants can increase the rate of the chemical reaction.
How is heating related to a substance's temperature?
As an object is heated, the rate of increase in temperature is proportional to the rate of heat added. The proportionality is called the heat capacity. Because the heat capacity is actually a function of temperature in real materials, the total amount of energy added will be equal to the integral of the heat capacity function over the interval from the initial temperature to the final temperature. If you just assume an average heat capacity over the temperature range, then the rise in temperature will be exactly proportional to the amount of heat added.
What would increase the pressure of gas in a container?
Any of the following: increasing the amount of gas; increasing the temperature; reducing the volume.
What does it mean to say that a material has a high or low capacity?
The specific heat capacity of a substance is the amount of energy required to increase the temperature of a said substance 1o K. The capacity is measured in kilojoules divided by kilogram time degrees Kelvin (kJ/Kg k). So, if the specific heat capacity of a substance is high, it requires a very large amount of energy to increase the temperature, and if it has a low specific heat capacity, the required energy will be lower.

Can coldness affect a city's electricity?
Yes, temperature does effect the conductivity of materials. For conductors, an increase in temperature reduces the current carrying capacity and does just the opposite in insulators.
