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.
What will increase the rate at which substances condenses?
increasing the temperature
How does an increase in temperature account for the fact that substances change state?
An increase in temperature changes the state because it melts it
When a volume of air is compressed its temperature does it increase or decrease or neither?
There is a thing called the "heat of compression" which causes all compressed substances to increase in temperature.
What is the amount of heat needed to increase the temperature of a certain mass of a substance by 1 degree Celsius?
The heat capacity of a substance is the amount of heat required to raise the temperature of a defined amount of pure substances by one degree (Celsius or Kelvin). The calorie was defined so that the heat capacity of water was equal to one.
Thermal energy added to a substance that is not changing state causes the substances temperature to do what?
To increase.
How does a substances temperature change when the average kinetic energy of it's particles increases?
As the average kinetic energy of a substance increases, the temperature will increase.
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!
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.
What are the symptoms of overdose of substances with stimulatory effects?
Substances with stimulatory effects may dangerously increase the heart rate and blood pressure, increase body temperature, and cause bizarre behavior. With cocaine, there is a risk of stroke.
What is the effect of pyrogen secretion?
Pyrogens are substances that cause the temperature set-point of the body to increase. They cause fever.
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!
