What mass of natural gas CH4 must you burn to emit 270kJ of heat?
To calculate the mass of natural gas burned, we need to use the heat of combustion of methane, which is -890 kJ/mol. This means that 1 mol of CH4 produces 890 kJ of heat. Therefore, to emit 270 kJ of heat, you would need to burn 270/890 = 0.303 mol of CH4. The molar mass of CH4 is 16.05 g/mol, so the mass of CH4 needed would be 0.303 mol * 16.05 g/mol = 4.86 g.
What is the formula for finding the mass in specific heat?
The formula for finding mass using specific heat is: mass = (heat energy)/(specific heat x change in temperature). This formula is derived from the specific heat equation, q = mcΔT, where q represents heat energy, m is mass, c is specific heat, and ΔT is the change in temperature. By rearranging the equation to solve for mass, we can determine the mass of a substance based on the amount of heat energy supplied, the specific heat capacity of the material, and the resulting change in temperature.
Can a fire burn and not give off light?
Yes! Pure Hydrogen is a great example of a gas that burns with a clear flame. As it pertains to burning stars that do not emit light, modern radio telescopes have confirmed the presence of thousands of stars in distant galaxies that do not give off light, but are visible to radio telescopes as giving off energy as expressed in x-rays and gamma rays. The existence of these lightless stars can also be proven based on the gravity that they have due to their large mass; and this gravity can be seen acting on other celestial bodies. -Benjamin B.
What happens to heat capacity if mass id doubled?
If the mass is doubled, the heat capacity will also double. Heat capacity is directly proportional to mass, as it is a measure of the amount of energy needed to increase the temperature of an object by a certain amount. More mass means more energy is required to raise the temperature.
how many blackhole mass is sol mass?
A black hole with the same mass as our Sun (1 solar mass) would be considered a stellar-mass black hole. These black holes form from the remnants of massive stars that have gone supernova. Their size and gravitational effects are determined by their mass and not their color, as they are truly black and do not emit light.

Can bio mass energy be converted into Heat energy?
Sure, burn it.
How is the different from the planets?
The Sun is a star, which means that it is made up of mostly Hydrogen and has enough mass to carry out nuclear reactions within its core and emit its own light and heat. The planets, even the gas giants, do not have enough mass to burn and glow on their own. There are more differences, but they vary from planet to planet.
A paraffin wax candle is used to heat up a can of water. The candle had a mass of 15.75g before the burn and 14.20g after the burn The can contained 250.0 of water at an initial temperature of 13.0 C?
A paffin wax candle is used to heat up a can of water. The candle had a mass of 15.75g before the burn and 14.20g after the burn. The can contained 250.0 of water at an initial temperature of 13.0 C. What is the heat of combustion in kJ/g of paraffin? The specific heat capacity of water is 4.184 J/(g C)
70 percent of sun's mass consists of?
Hydrogen, specifically hydrogen nuclei undergoing nuclear fusion to form helium. This process releases energy in the form of heat and light, which powers the Sun and allows it to emit sunlight.
What happens after a medium mass star becomes a white dwarf?
Nothing. It will just slowly and I mean very slowly, emit heat back into space. This will take billions and billions of years. After it has cooled to a point where no heat is emitted into space it will become a black dwarf.
When you burn logs does mass or volume change?
When logs are burned, the mass remains the same but the volume decreases. This is because the burning process releases the stored energy in the logs in the form of heat and light, but the total amount of matter in the logs is conserved.
How much does the suns mass decrease every second in tons?
The Sun loses about 4.2 million tons of mass every second due to nuclear fusion reactions in its core converting hydrogen into helium. This mass loss is converted into energy, which is what powers the Sun and allows it to emit light and heat.
What is the relationship between the mass of a material and the amount it can transfer?
Heat is transferred based on the temperature of a mass (relative to the cooler mass it is transferring heat to) and the heat capacity of the mass. The total heat capacity is a product of the mass and the specific heat, i.e. Heat capacity = mass x specific heat. The hotter the mass, the more heat it can transfer. The greater the mass, the more heat it can transfer per degree of temperature drop. 100 kg of boiling water could be expected to be able to transfer 100 times the amount of heat of just 1 kg of boiling water for a drop of 1 °C.
