Question

1. ejercicio múltiple 1 punto which of these changes will decrease the pressure of a gas? increase the number of gas particles increasing the volume decreasing the volume increasing the temperature 3. respuestas múltiples 1 punto which phase(s) of matter have particles arranged in a regular pattern? liquid gas solid 4. fórmula 1 punto convert - 3°c to k. use whole numbers for your answer. respuesta 270 15

Explanation:

Step1: Recall gas - law relationships

According to the ideal gas law $PV = nRT$ (where $P$ is pressure, $V$ is volume, $n$ is the number of moles of gas, $R$ is the ideal - gas constant, and $T$ is temperature in Kelvin). An increase in volume ($V$) while keeping $n$ and $T$ constant will decrease the pressure ($P$).

Step2: Analyze particle - arrangement in matter

In solids, the particles are arranged in a regular, repeating pattern. In liquids, the particles are close together but can move past each other, and in gases, the particles are far apart and move freely.

Step3: Convert Celsius to Kelvin

The conversion formula from Celsius ($T_C$) to Kelvin ($T_K$) is $T_K=T_C + 273.15$. Given $T_C=-3^{\circ}C$, then $T_K=-3 + 273.15=270.15$. Rounding to a whole number, $T_K = 270$.

Answer:

1. Increasing the volume
2. Solid
3. 270
