	Helium. Who is Helium? What is Helium? Where is Helium? Definition of Helium. Meaning of Helium.
		The specific heat capacity of helium gas is very high and helium vapor is very dense, expanding rapidly when it is warmed to room temperature.
		Specifically, it is found in minerals of uranium and thorium, such as clevites, pitchblende, carnotite, monazite and beryl; it is produced from these elements by radioactive decay in the form of alpha particles.
		Since the transformation is one of higher order, without latent heat at the lambda point, the two liquid forms never coexist.

		Thus, an order of magnitude is an approximate position on a logarithmic scale.
		An order of magnitude estimate of a variable whose precise value is unknown is an estimate rounded to the nearest power of ten.
		For example, an order of magnitude estimate for a variable between about 3 billion and 30 billion (such as the human population of the Earth) is 10 billion.

	Spirax Sarco Learning Centre: 2.2 - Steam Engineering Principles and Heat Transfer: What is Steam?
		Heat that breaks the lattice bonds to produce the phase change while not increasing the temperature of the ice, is referred to as enthalpy of melting or heat of fusion.
		This may be considered as the useful portion of heat in the steam for heating purposes, as it is that portion of the total heat in the steam that is extracted when the steam condenses back to water.
		This is because the specific enthalpy of evaporation decreases as the steam pressure increases.

	Henry Wallace: Kinemassic Force Field
		The relative magnitude of the undulating kinemassic force field and the kinemassic permeability characterizing the associated structure are both influential in determining the effective shielding of the kinemassic field permeable structure.
		These temperature corrections account for the heat applied to the system, as well as that due to the change in specific heat property of the apparatus due to frictional heating, as well as that due to the change in specific heat property of the apparatus, principally the brass members die to their relative bulk.
		In order to substantiate the distance dependency of the gravitational coupling force due to the dynamic interaction of relatively moving bodies it was predicted that increasing the separation between the generator rim flange 21a and the cooperating surface of the pole pieces 23a should measurably reduce the results obtained.

		The laser energy manifests itself in the form of heat, and the thermal effects of nanosecond laser irradiation can be determined by the solution of one-dimensional heat flow equation with appropriate boundary conditions, while taking into account the phase changes occurring in the material.
		A three-dimensional solution is not required because of the very short processing times (~200 ns) and the large transverse dimensions of the laser beam, which result in thermal gradients many orders of magnitude greater in the perpendicular direction to the surface than compared to the transverse directions [3,4].
		To solve Equation (1), we have adopted a higher order implicit finite difference method in which the thermal gradients at the interface are accurately determined for calculating the interfacial velocity[4].

		I have no idea what is the heat capacity of fully ionized hydrogen is, but I would not want to be on the same city block with that pinhead.
		The specific density of hydrogen at sun's core is 150.
		The specific heat of hydrogen is 14304 Joules per kg per degree K. Core temp is 15 million C. So 1 mm^3 hydrogen at that pressure is 0.15 grams, and specific heat is 14.304 Joules per g per degree K. 14.304 J/g/K * 15e6 K * 0.15 g = 32 megajoules.

		Note that while the peak power of the output pulses for a Q-switched laser may be many orders of magnitude greater than with the Q-switch disabled or bypassed, for the fundamental output wavelength (e.g., 1,064 nm for a Nd:YAG laser), the total energy (pulsed) or average power (quasi-CW) is generally lower.
		The numbers I have seen are on the order of about 30 mW out for 1 W of diode pumping (efficiency is much higher with Ti:Saph pumping, but it's kind of inconvenient to have a such a laser pump a 100 mW 532 nm system, not to mention expensive.
