What stays constant in adiabatic process? Adiabatic free expansion of a gas For an ideal gas, the temperature remains constant because the internal energy only depends on temperature in that case. Since at constant temperature, the entropy is proportional to the volume, the entropy increases in this case, therefore this process is irreversible. How is […]
What do you understand by state of a system and state variables?
What do you understand by state of a system and state variables? A state variable is one of the set of variables that are used to describe the mathematical “state” of a dynamical system. Intuitively, the state of a system describes enough about the system to determine its future behaviour in the absence of any […]
What happened to the distance between two straight conductor carrying current in the same direction?
What happened to the distance between two straight conductor carrying current in the same direction? The force acting on one wire due to currents through two wires is inversely proportional to the distance between them. Thus the force becomes 1/2 times if the distance between the wires is doubled. When a coil carrying current is […]
Is calcium a covalent or ionic bond?
Is calcium a covalent or ionic bond? Calcium carbonate is another example of a compound with both ionic and covalent bonds. Here calcium acts as the cation, with the carbonate species as the anion. These species share an ionic bond, while the carbon and oxygen atoms in carbonate are covalently bonded. What type of bond […]
How do you calculate scalar product?
What is the symbol of Curie?
What is the difference between meiosis I and meiosis II?
What is the difference between meiosis I and meiosis II? Homologous pairs of cells are present in meiosis I and separate into chromosomes before meiosis II. In meiosis II, these chromosomes are further separated into sister chromatids. Meiosis I includes crossing over or recombination of genetic material between chromosome pairs, while meiosis II does not. […]
Which of the following is NOT component of physical fitness?
Which of the following is NOT component of physical fitness? Answer. Anaerobic capacity is not a measure of physical fitness as it cannot be used to measure the fitness metrics of a person. Agility is the measure of a person to move fast and run well. Flexibility is the ability of a person to twist […]
When resistance increases what happens to voltage?
When resistance increases what happens to voltage? This means that if the voltage is high the current is high, and if the voltage is low the current is low. Likewise, if we increase the resistance, the current goes down for a given voltage and if we decrease the resistance the current goes up. Does increasing […]
