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.
Element which possess different number of "Neutrons" in different situations could be an isotope of the atom
Ex. - 17 Cl 34, 17 Cl 35, 17 Cl 36
They all the isotopes.
Hope this helps!
Answer:
0.1
Explanation:
I know that because of the law of conservation of mass
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.
So, the final pressure is equal to 362.7 Pa.
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
