Fourier's Law: Q = -kA(dT/dx), where Q is the heat flow rate, k is the thermal conductivity of the material, A is the cross-sectional area, and dT/dx is the temperature gradient.

What is the average speed of gas molecules in a given sample at a specific temperature and pressure?

The average speed of gas molecules in a sample at a certain temperature and pressure is determined by the kinetic theory of gases. This speed is directly proportional to the square root of the temperature and inversely proportional to the square root of the molecular weight of the gas.


If you have three liters of gas at a certain kelvin temperature and a certain pressure. The kelvin temperature triples and the pressure stays the same. What is the gas volume?

According to Charles's Law, the volume of a gas is directly proportional to its Kelvin temperature when pressure is constant. Therefore, if the Kelvin temperature triples, the gas volume will also triple, so the gas volume will be 9 liters.


What is the relationship of mass an object to the amount of heat required to change its temperature?

The amount of heat required to change the temperature of an object is directly proportional to its mass. This means that the larger the mass of an object, the more heat is needed to change its temperature by a certain amount.


Is frequency proportional to distance?

No, frequency is not directly proportional to distance. The frequency of a wave is determined by its source and is not directly related to the distance it travels. However, factors such as the medium through which the wave travels can affect its frequency.


How does temperature difference affect the rate of heat transfer?

FACTORS AFFECTING HEAT TRANSFERTemperature Difference (.T ) between the two fluids - This is the driving force in heat exchange principles. The greater the .T, the greater the heat transfer rate .Fluid flow rate - Increasing flow rate will increase heat transfer rate.The nature of the heat conducting materials - Some materials have a high conductivity while others don't. This factor is 'built-in' in the design of the Exchanger and choice of materials. It is governed by the design engineers before manufacture.Surface area - The larger the surface area of the conducting interfaces, the greater the heat transfer rate.The surface area, again, is controlled by the design and manufacture of the exchanger. The more tubes contained in the bundle, the greater the surface area. The tube length will also affect heat transfer, as will the outside diameter and metal thickness of the tubes.

What is the difference between long hand and short hand writing?

Longhand are words we use everyday - like "cat", "dog", etc. Shorthand writing is using certain symbols as "shortcuts" for not having to write down the entire word. Also, silent letters are omitted, leaving only the sounds of the word, such as the word "Humble" - a stenographer (one who writes in shorthand) would not include the "e". That is the main difference between shorthand and longhand.


What is the difference between proportional and nicht proportional font scripts?

Proportional means that different letters have different widths. The font used in typewriters (and in fonts like Courier New) have a fixed width, making it easier to align certain kinds of data. But it looks ugly.


What is the difference between proportional and non proportional relationship?

In mathematics, or physics, if one quantity is proportional to the other, that means that if one quantity increases by a certain factor, the other quantity increases by the same factor. For example, if"y" is proportional to "x", and "x" increases by a factor 10, then "y" must also increase by a factor 10. Any relationaship that does NOT follow this rule is NOT proportional.

What is voltage equivalent of temperature?

The voltage equivalent of temperature is often represented through the concept of thermoelectric effects, particularly in thermocouples, where a voltage is generated in response to a temperature difference. This relationship is described by the Seebeck effect, where the voltage produced is proportional to the temperature gradient. In thermodynamics, temperature can also be expressed in terms of energy per unit charge, linking it to the concept of voltage in certain contexts, such as in the behavior of semiconductor materials. Overall, while not directly equivalent, voltage can serve as an electrical representation of temperature in specific applications.


Can you be injured from opening the refrigerator after being in heat?

If you mean if you are in a heat wave then yes. the sudden temperature change can stop your heart if you are past a certain age, depending on the difference in temperature.


How superconductivity relates to ohm's law?

Ohm's law states that the current flowing through a conductor is directly proportional to the voltage applied across it and inversely proportional to its resistance. Superconductivity is a property observed in certain materials where they exhibit zero electrical resistance below a critical temperature. In superconductors, Ohm's law is not applicable as there is no resistance to impede the flow of current, resulting in the potential for an infinite current to flow in a closed circuit without needing a voltage difference.


What is the difference between certain and for sure?

There is no difference between "certain" and "for sure."


Does the temperature of water affect the growth of water?

Within a certain temperature range, there should be no difference. Though I suppose if you are planning to water your flowers with boiling water, just hope you don't damage the roots or something.
