When you increase the volume with constant temperature, what happens

Physics

Answer:

Pressure increases

Explanation:

"Gay Lussac's Law - states that the pressure of a given amount of gas held at constant volume is directly proportional to the Kelvin temperature. If you heat a gas you give the molecules more energy so they move faster. This means more impacts on the walls of the container and an increase in the pressure."

When this occurs the pressure will increase because temperatures will follow with pressure along with pressure following temperatures

A skateboarder coasts a distance of 20 meters in 4 seconds. What is the person's speed?
MrMuchimi

Answer:

5 m/s

Explanation:

The formula of speed is : distance/time taken.

The skateboarder covered a distance of 20 meters in 4 seconds. So,

Distance = 20 meters

Time Taken = 4 seconds

Speed = 20/4 = 5 m/s

Una cantidad de aire se lleva del estado a al estado b siguiendo una trayectoria recta en una grafica PV como es mostrado en la
allochka39001 [22]

Answer:

El trabajo de frontera ejercido por el gas es 10,297.875 joules.

Explanation:

Supongamos que el gas se comporta idealmente y que el proceso es isotérmico y adiabático. El trabajo efectuado por el gas en el proceso equivale al área bajo la curva de la gráfica PV. Puesto que es una línea recta y que tanto la presión como el volumen son variables positivas, tenemos que esa área es la suma del rectángulo inferior (límite inferior de la presión) y el triángulo superior (entre los límites inferior y superior de la presión). Es decir:

W = P_{min}\cdot (V_{2}-V_{1})+\frac{1}{2}\cdot (P_{max}-P_{min})\cdot (V_{2}-V_{1}) (1)

Donde:

W - Trabajo de frontera ejercido por el gas, medida en joules.

V_{1}, V_{2} - Volúmenes del gas antes y después de la expansión, medidas en metros cúbicos.

P_{min} - Límite inferior de la presión del gas, medida en pascales.

P_{max} - Límite superior de la presión del gas, medida en pascales.

Si sabemos que V_{1} = 0.06\,m^{3}, V_{2} = 0.13\,m^{3}, P_{min} = 125,432\,Pa y P_{max} = 168,793\,Pa, entonces el trabajo de frontera ejercido por el gas es:

W = (125,432\,Pa)\cdot (0.13\,m^{3}-0.06\,m^{3})+\frac{1}{2}\cdot (168,793\,m-125,432\,m) \cdot (0.13\,m^{3}-0.06\,m^{3})

W = 10,297.875\,J

El trabajo de frontera ejercido por el gas es 10,297.875 joules.

A square coil of wire with side 8.0 cm and 50 turns sits in a uniform magnetic field that is perpendicular to the plane of the c
bezimeni [28]

Answer:

Explanation:

area of the coil  A = .08 x .08 = 64 x 10⁻⁴ m ²

flux through the coil Φ = area of coil x no of turns x magnetic field

= 64 x 10⁻⁴ x 50 x B where B is magnetic field

emf induced = dΦ / dt = ( 64 x 10⁻⁴ x 50 x B - 0 ) / .2

= 1.6 B

current induced = emf induced / resistance

12 x 10⁻³ = 1.6 B / 15

B = 112.5 x 10⁻³ T .
