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
Water requires more energy than an equal mass of iron for its temperature to increase by a given amount because water has a greater?
Water has a greater specific heat capacity.
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 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 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.
How does the air's capacity to hold water change as elevation increase?
As elevation increases, temperature decreases approximately at the rate of 12.5 degrees c every 1km upwards. As air temperature decreases, its capacity to hold water is less. Therfore as elevation increases, its water capacity will decrease.
Will concrete brick aluminum or copper take most energy to increase its temperature?
Whichever of them has the lowest specific heat capacity will take the least energy to raise its temperature, and whichever has the highest specific heat capacity will take the most energy.

What does it mean to say that the specific heat capacity of water is greater than that of iron?
Heat capacity is the amount of heat needed to increase the temperature of an element (a given mass) by a temperature unit.Specific Heat Capacity is the amount of heat in Joulesneeded to heat 1kg of an element by 1 degree Kelvin.Joules per Kilogram KelvinIf the SHC of water is higher than that of iron, it means, you need more heat to increase the temperature of 1kg of water in 1 degree Celsius, than the heat you need to increase the temperature in 1 degree Celsius of the same mass of iron.P.S.A Celsius temperature difference is the same as a Kelvin temperature difference. In measuring SHC, we only need to focus on temperature difference rather than the temperature value. Add 273.15 to the Celsius measurement of the temperature to get the Kelvin temperature value.
