Makes it seem bigger and brighter

When the size of a star increases, the brighter it gets.

The color of the star is determined by the temperature.

If the temperature of the star is lower, that means the star is an orange/red color.

If the star's temperature is higher, that means the star is an blue/white color.

The thermal energy of a substance is related to the movement of the particles in the substance. This energy is defined by the temperature of the substance and whether heat is transferred or lost. This can be explained as a higher temperature causes the particles in substances to move faster and collide.

Answer:

Final pressure = 362.7 Pa

Explanation:

Given that,

Initial volume, V₁ = 930 ml

Initial pressure P₁ = 156 Pa

Final volume, V₂ = 400 mL

We need to find the final pressure. We know that the relation between volume and pressure is inverse i.e.

V\propto \dfrac{1}{P}\\\\\dfrac{V_1}{V_2}=\dfrac{P_2}{P_1}\\\\P_2=\dfrac{V_1P_1}{V_2}\\\\P_2=\dfrac{930\times 156}{400}\\\\P_2=362.7\ Pa

So, the final pressure is equal to 362.7 Pa.

The melting of ice is an example of a process that is: Select the correct answer below: always spontaneous always nonspontaneous
kolezko [41]

Answer:

Option C, spontaneous or nonspontaneous depending upon the temperature of the surroundings and pressure

Explanation:

AT room temperature, the temperature is favorable for ice to melt and hence melting of ice at room temperature is spontaneous but when the temperature is below the melting point and even then the ice melts then it is called non spontaneous. In this case, the enthalpy and entropy together create a positive change in the free energy for melting.

Hence, option C is correct
