Why is there a lower limit on the mass that a star may have?
It's because a gas cloud has to have a critical mass in order to generate enough temperature to start the nuclear processes that enable the star to radiate heat and light.
What is specific heat capacity and what does it measure?
Specific heat capacity(q) is the amount of heat needed to raise a tamperature of a body with mass of 1kg by 1K or 1 decree celcius. The formuale to calculate it is c(specific heat capacity) = Q/mass x change in temperature.
When the mass of one object is considerably Less than the mass of another object is the action-reaction force not noticeable?
If the MASS of the 1st Object in a COLLISION is too small to generate a FORCE large enough to overcome the INERTIA of the 2nd Object, then the more massive Object will not move. This could make it look like the more massive object is not REACTING to the Collision.
The amount of energy needed to change a given mass of ice to water at constant temperature is called the heat of condensation crystallization fusion formation?
fusion
Why does mass count in heat transfer?
Mass counts because when you have a block of some material at some heat. Then that is the average heat of every molecule in that block. The more mass there is the more energy is available to be transfered as heat.
What element does a low mass star stop at and why?
Helium. A low mass star does not have enough mass to generate the heat needed to fuse helium.
Do nuclear reactors have critical mass?
We know that critical mass can be achieved in a nuclear reactor. If it could not, we'd not be able to get a chain reaction and generate heat to generate power. Reactors don't have critical mass when the control rods are in, but pull the rods, start the reactor up and away you go!
What type of energy needs very little mass?
Nuclear energy is a type of energy that needs very little mass. Nuclear energy is used to generate electricity and heat.
Which muscle fiber helps generate heat for the body?
The skeletal muscles are responsible for heat generation in the body. This is because they account for 40% of body mass and are required for maintaining body temperature.
What mass of natural gas CH4 must you burn to emit 270kJ of heat?
The needed mass of methane is approx. 3 g.
What is the purpose of a biomass boiler?
The purpose of a biomass boiler is to generate heat by burning or converting mass to energy. It does this in an efficient and environmentally friendly manner.
How much heat is needed to heat a copper penny from 30 to 35 degrees Celsius?
You need to know the mass of this coin.Heat (in calories) = 5 x 0,092 x mass (in g)
Why is there a lower limit on the mass that a star may have?
It's because a gas cloud has to have a critical mass in order to generate enough temperature to start the nuclear processes that enable the star to radiate heat and light.
What is specific heat capacity and what does it measure?
Specific heat capacity(q) is the amount of heat needed to raise a tamperature of a body with mass of 1kg by 1K or 1 decree celcius. The formuale to calculate it is c(specific heat capacity) = Q/mass x change in temperature.
What are the factors that determine the amount of energy needed to raise the temperature?
Mass, heat capacity, the desired raise in temperature.
When the mass of one object is considerably Less than the mass of another object is the action-reaction force not noticeable?
If the MASS of the 1st Object in a COLLISION is too small to generate a FORCE large enough to overcome the INERTIA of the 2nd Object, then the more massive Object will not move. This could make it look like the more massive object is not REACTING to the Collision.
What is the amount of energy needed to change the temp of a substance called?
The specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius
