How can the enthalpy of air be calculated?

The enthalpy of air can be calculated using the equation: enthalpy internal energy pressure volume. This equation takes into account the internal energy of the air and the pressure and volume of the system.


What is the energy of travels through space as waves?

Electromagnetic waves carry energy through space. This energy takes the form of photons, which are massless particles that move at the speed of light. The energy of electromagnetic waves is directly proportional to their frequency, according to Planck's equation.


What is the energy change takes place in microphone?

In a microphone, sound waves create vibrations in a diaphragm which convert acoustic energy into mechanical energy. This mechanical energy is then transformed into electrical energy through a transducer, which produces an electrical signal that represents the sound wave.


What does d stand for in kinematic equation?

In kinematic equations, the variable "d" typically represents displacement, which is the change in position of an object. Displacement is a vector quantity that takes into account both the magnitude and direction of the movement.


What happens to the mass of the sun that is lost during fusion?

Albert Einstein is credited with the equation that explains how the process of fusion provides energy. His equation, E = mc2 , stated that matter can be converted into energy and vice versa. In the fusion process that takes place in the sun, the hydrogen at the start of the process has more mass than the helium at the end of the process. Einstein explained that the lost mass is not actually lost, but has been converted to energy. This energy is the solar wind.

What equation represents the energy it takes to heat up a substance?

There are many equations that represent the energy it takes to heat up a substance, depending on which aspect of "heating" you refer to. Probably the one in question here is q = mC∆T where q = amount of heat energy; m = mass of the object; C = specific heat of that object; ∆T= change in temperature.

What process does the following word equation represent enzymes?

The word equation "substrate + enzyme = product" represents the process of enzyme-catalyzed reactions. Enzymes are proteins that act as biological catalysts, speeding up chemical reactions by lowering the activation energy required for the reaction to occur. Substrates bind to the enzyme's active site, where the reaction takes place to form products.

What is an equation that is parallel to -3x 1 on a graph?

y = -3x + 7 is an equation which gives us a line parallel to the line y = -3x + 1, or the line -3x - 1. The equation given represents the slope-intercept form of the equation for a line. Slope-intercept takes the form y = mx + b. In this form the the value of m represents the slope of the line, while b represents the Y intercept. All lines with the same slope are parallel (unless they're exactly the same.) So to find a parallel line, we simply adjust the Y intercept to any value other than the one given.

How do you calculate the activity coefficient in a solution?

To calculate the activity coefficient in a solution, you can use the Debye-Hckel equation. This equation takes into account the charges and sizes of ions in the solution, as well as the temperature and ionic strength. By plugging in these values, you can determine the activity coefficient, which represents the deviation of the solution from ideal behavior.
