Ice melts at o degree centigrate the temperature remain constant at o degree centegrate until all the ice has melted suggest why the temperature remains constant during melting although heat is abs?
At melting point of a substance the supplied heat is utilized to change the state so temperature remains constant till all the material is converted into liquid, this is known asLatent heat of fusion.
What maintains stable conditions inside the body?
There are far more than three conditions that are controlled inside your body. Examples are temperature, oxygen level, blood sugar level, pH of our blood, blood electrolyte levels, heart rate, and muscle tone. The maintenance of a relatively stable body state is known as homeostasis.
How can the concentration of electrons and holes remain constant at a particular temperature?
The holes and electrons, together, can be found particularly in tetravalent elements like Si and Ge. It is experimentally verified that at -2730K temperature, that is at absolute zero temperature, such elements behave like a perfect insulators. Now when temperature increases, some of the valence electrons escape into conduction band, producing a vacancy at their respective places. These vacancies are known as holes. Thus the number of hole-electron pairs always remain constant. Thus the concentration of electrons and holes remain constant at any temperature.
At a constant pressure how does a volume of gas vary with respect to the absolute temperature?
It doesn't. The equation for mean free path is: mfp = 1 / [sqrt(2)*n*pi*d^2] In the above equation, n is the number of molecules per unit volume, and d is what is known as the collision diameter (the distance between the centers of the two colliding molecules). Thus, there are only three variables which affect mean free path: number of molecules, volume, and collision diameter. Volume can be changed by a change in temperature, but this question assumes constant volume (meaning pressure will change as temperature changes). As long as the amount of gas is unchanged, the mean free path will be unaffected by changes in temperature. This is a wrong answer. The collision diameter decreases with the increase of temperature.
What is the following is an expression of Charles law?
V/T = constant
Why does the temperature of the planet remain in a constant balance?
It doesn't. This is known as "climate change".
What usually happens in general for a gas at a constant volume?
The gas volume become constant when the pressure is increased to a point that makes the distance between the gas molecules equal to zero at this point no more increase of temperature with pressure is observed. Or if the pressure and temperature are kept constant within a system then the volume can also be constant as long as you are able to maintain the pressure and temperature at constant level.

What does constant mean in an algebraic expression?
A constant in an algebraic expression is a number that does not change. For example x + 2 The 2 is a constant (does not change) x is a variable (can take on any value)
What law describes the relationshp between volume and temperature of a gas when pressure is constant?
When the pressure is constant, the law describing the relationship between volume and temperature is known as Charles' Law: V1/T1 = V2/T2
What is the formula for Gay-Lussac?
Gay-Lussac's Law states that the pressure of a sample of gas at constant volume, is directly proportional to its temperature in Kelvin. The P's represent pressure, while the T's represent temperature in Kelvin. P1 / T1 = constant After the change in pressure and temperature, P2 / T2 = constant Combine the two equations: P1 / T1 = P2 / T2 When any three of the four quantities in the equation are known, the fourth can be calculated. For example, we've known P1, T1 and P2, the T2 can be: T2 = P2 x T1 / P1

What is the formula for finding pressure?
I suppose you mean the formula for the variation in pressure. The simplest expression of this is, at a fixed temperature,and for a given mass of gas, pressure x volume = constant. This is known as Boyle's Law. If the temperature is changing, then we get two relations: 1. If the pressure is fixed, volume = constant x temperature (absolute) 2. If the volume is fixed, pressure = constant x temperature (absolute) These can be combined into the ideal gas equation Pressure x Volume = constant x Temperature (absolute), or PV = RT where R = the molar gas constant. (Absolute temperature means degrees kelvin, where zero is -273 celsius)
