Does wind move in a straight line?
No. It is affected by localised pressure differences, thermals - which depend on the the heat-retention property of the surface, surface contours (including man-made ones).
Disadvantages of heat?
The disadvantages of heat are that if there is no solar energy, then there is no heat.
How are heat and temperture different?
heat is considered a position of higher temperature.... Temperature on the hand is only a measure of a heat condition
What size heat pump for 2800 sq ft?
In a Cold Climate and Hot Climate: Each ton of heat pump capacity can heat/cool approximately 500-600 square feet.In a Moderate Climate: Each ton of heat pump capacity can heat/cool 600-700 square feet.So either a 5.0 ton heat pump in a cold climateor a 4.5 ton heat pump in a moderate climate.
Is heat a scalar or vector?
Heat is energy. It and temperature are both scalars.
Why does heat travel in straight lines?
cuz it does
Why does heat travel in astraight line in radiation?
Radiant heat (from the sun or electric fire) is infra red radiation and behaves like light, travelling in straight lines unless reflected of refracted. Conducted heat as in a metal wire is basically energy of thermal vibration and this energy is passes from atom to atom in the material.
Why if your hand is held near to the side of a flame does the front of your hand feel heat?
Mostly the heat you feel will be radiation from the flame, which travels in straight lines. Thus it hits the side of the hand nearer the flame.
What would happen if the planets do not have their own orbit?
Without the Sun's gravity and heat they would all go off in straight lines and freeze up solid.
How come light travels in straight lines but radio waves spread out?
Light and Radio Waves are both forms of Electromagnetic radiation, and propagate at c (that is, the speed of light, 3*10^8m/s). Both light and radio waves can travel in straight lines, or by spreading out, depending on how they are made. For example, a radio dish and a light bulb can both spread out light and radio waves in 360 degrees.
Does conduction require direct contact?
convection requires a medium to travel. In space there is no air but, a vacuum. Therefore direct heat from the sun is radiation as it does not require a medium to travel.
What are the problems of heat exchangers?
blocked lines and wear of lines are the most important problems of heat exchangers.
Does heat travel in waves or straight lines?
Radiant heat is subject to the weird physics of electromagnetic radiation like light and has dual wave and particle properties. In this case the answer would be "yes" (it travels in a straight line as if by particle AND as a wave) In the case of conduction, it moves according to the structure of the material that it is moving through. The heat is transferred as molecules of higher kinetic energy collide with molecules of lower kinetic energy. On a macroscopic level this looks like the heat moving in a straight line - although if the source of sink for the heat is not a flat surface, the isotherms - the imaginary shells or surfaces that would be defined if you graphed in three dimensions where the temperature is the same - can look a lot like waves.
How can heat and sound energy travel?
They travel in waves.
Why lines of latitude carve out the heat zones of the earth?
lines of latitude carve out the heat zones of the earth give reason
Does sound travel faster in heat or water?
Sound doesn't travel in heat. It travels in a physical medium.
Can heat travel through a vaccume by radiation only?
Rradiation is the only way that heat can travel in a vacuum.
