q = mass * specific heat * change in temperature
428 joules = (mass)(0.385 J/gC)(25o C)
= 44 grams copper
============
Depends, what do you mean "change"? Atomic mass "changes" whenever something undergoes decay or breaks apart. In this respect, atomic mass is not exactly conserved either. Rest mass gets converted to energy; e=mc^2, meaning energy is equal to mass times the speed of light squared. This energy is usually the kinetic energy of the particle that gets dislocated from the original atom.
If you want to be pedantic, scientists measure temperature in kelvins, not degrees. Heat is energy and is measured in energy units, like joules.
Degrees
Thermal energy (heat)
You mean how much heat energy will be lost/transferred as you are losing Joules here. All in steam, so a simple q problem and no change of state. 2.67 kg = 2670 grams q = (2670 grams steam)(2.0 J/gC)(105 C - 282 C) = - 9.45 X 105 Joules ----------------------------------- This much heat energy must be lost to lower the temperature of the steam.
Energy.
b
Energy can either be soaked up by the matter in the process of making the change (melting), or be released from the matter during the change (fire).
An energy transformation.
You look up the specific heat of copper (per mass unit). Then you multiply specific heat x mass x temperature difference.
You cannot. You need the mass of the piece of copper.
The HVL doesn't change. The thickness of Al or Cu used to determine HVL will change as energy changes. At any energy you are able to state HVL in terms of Cu or Al.
Living beings are, in a way, similar to engines, and they need fuel - for example, to move around, to grow, etc. Without energy, no change is possible. A lifeless statue doesn't need energy; anything that moves, grows, or undergoes any other type of change, does.
rotate the energy ring 180 degrees
O.385x1x2=0.77 Answer: 0.77
It depends on the specific energy of the substance.
in a nuclear reaction, matter (atoms) will be converted to energy. Other than that, no. That is called the conservation of mass.
