What else can I help you with?
When a sealed Thermos bottle full of hot coffee is shaken what are the changes if any in a the temperature of the coffee b the internal energy of the coffee?
There is a large increase in the temperature of the coffee due to the large amount of kinetic energy inputed into the system through the shaking motion. Thus due to the heat being released there is a large decrease in the internal energy of the system
A person shakes a sealed insulated bottle containing hot coffee for a few minutes what is the change in the temperature of the coffee. what is the change in the internal energy of the coffee?
There is a large increase in the temperature of the coffee due to the large amount of kinetic energy inputed into the system through the shaking motion. Thus due to the heat being released there is a large decrease in the internal energy of the system.
Why does a semiconductors ability to conduct electricity increase when temperature rises?
if we increase the temp so large no of electrons jumbs from valence energy band to conduction energy band .when there are alarge no of electrons in conduction band to the conduction increase means this simiconductor can conduct easyly. thanx Engr Bashir Khan.
How do you define 1calorie?
The large calorie, kilogram calorie, dietary calorie or food calorie approximates the energy needed to increase the temperature of 1 kilogram of water by 1 °C.
What is the temperature in a substance with a large amount of thermal energy?
The temperature of a substance with a large amount of thermal energy will be higher compared to a substance with lower thermal energy. Thermal energy is directly related to temperature, so as the amount of thermal energy increases, the average kinetic energy of the particles in the substance increases, leading to a higher temperature.
Heat capacity is the characteristic of a material to?
absorb heat energy without undergoing a large increase in temperature. It is the amount of energy required to raise the temperature of a substance by a certain amount. Heat capacity is an extensive property and depends on the mass and specific heat capacity of the material.
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 is temperature different from heat?
Temperature is a method of measure used to express (in degrees) the amount of heat present in a substance. Much like weight is a method of measure used to express (in lbs or ozs) density of Matter.
What substance has a large amount of thermal energy?
Molten lava from a volcano has a large amount of thermal energy due to its high temperature.
Which planet has a large difference in temperature from one side of the planet to the other?
Mercury.
Materials with a high specific heat can absorb heat without a large what in temperature?
Specific heat is the amount of heat required to raise the temperature of a substance by 1 degree Celsius. Materials with a high specific heat can absorb a significant amount of heat energy without experiencing a large increase in temperature. This property makes them useful for applications like thermal buffering or regulation of temperature changes.
If a large at 30 degrees and a small bowl at 30 degrees which has the most heat energy in it?
Both the large and small bowl will have the same amount of heat energy if they are at the same temperature (30 degrees). The heat energy in an object depends on its mass, temperature, and specific heat capacity, but in this case, since both bowls are at the same temperature, they would have the same amount of heat energy.
