The higher the molar mass, the higher the melting point. This is because molecules with higher molar mass have stronger Van der Waal's (London) forces, making it more difficult to overcome(thus the higher melting point). However, this is true only when the Van der Waal's forces are the ONLY intermolecular forces.

How is temperature and thermal energy different?
Temperature is a measure of the average kinetic energy of the particles in a substance, while thermal energy is the total kinetic energy of all the particles in a substance. Temperature is an intensive property, meaning it does not depend on the amount of material present, while thermal energy is an extensive property, meaning it does depend on the amount of material present.
What is specific heat a measure of?
The amount of energy it takes to change the temperature of a substance by a certain amount. How much energy it takes to heat a substance ~APEX
Why do the densities of most substance decrease with temperature?
Most substances expand as they are heated, causing the atoms or molecules to spread out and the volume to increase. Since the mass remains constant, the density (mass per unit volume) decreases as the volume increases with temperature.
Q equals mass x specific heat x difference in temperature?
This formula relates heat (Q) with mass, specific heat, and temperature change. It is typically used to calculate the amount of heat energy gained or lost during a temperature change in a system. The formula shows that the heat exchanged is directly proportional to the mass of the substance, its specific heat capacity, and the temperature change.
What is the molar mass of sulfur?
The molar mass of sulfur is 32.065. Molar mass is the mass per mole of a substance. In other words, Molar Mass = Mass/Amount of Substance.
Does volume and mass depend on temp?
Yes, both volume and mass can depend on temperature. Volume can change with temperature due to thermal expansion or contraction, while the mass of a substance remains constant regardless of temperature. However, changes in temperature can affect the density of a substance, which is the mass per unit volume.
How are temperature and thermal energy different?
Temperature is a measure of the average kinetic energy of the particles in a substance, while thermal energy is the total kinetic energy of all the particles in a substance. Temperature is a single value that does not depend on the mass of the substance, while thermal energy is directly proportional to the mass of the substance.
What does heat capacity depend on?
Heat capacity depends on the substance's mass, the substance's specific heat capacity, and the temperature at which the substance is being heated. It is a measure of how much energy is required to raise the temperature of a substance by one degree Celsius.
What between an extensive and an intensive property?
Intensive properties do not depend on the matter's amount of the physical system (mass density, temperature ...). Extensive properties do depend on the amount of matter that is present (volume, mass and size).
Why does mass not depends on temperature?
Mass is a measure of the amount of matter in an object, and it remains constant regardless of temperature changes. Temperature affects the kinetic energy of particles in a substance, causing expansion or contraction, but it does not change the amount of matter present. Therefore, the mass of an object does not depend on its temperature.
What does heat content depend upon?
The heat content of a substance depends on its temperature, mass, and specific heat capacity. Temperature is a measure of the average kinetic energy of the particles in the substance, while mass determines the amount of substance present. Specific heat capacity is a material-specific property that quantifies how much heat energy is required to raise the temperature of a substance by a certain amount.
Does the volume of gas depend on its mass?
The volume of a gas does not depend on its mass. The volume of a gas is determined by factors such as temperature and pressure according to the ideal gas law, while the mass of a gas is a measure of the amount of substance present.
What are two physical properties that don't depend on size?
Density and melting point are two physical properties that do not depend on the size of a material. Density is the mass of a substance per unit volume, while the melting point is the temperature at which a substance changes from a solid to a liquid state.
What affect would an incorrect reading of temperature have on the molar mass?
An incorrect reading of temperature would not directly affect the molar mass of a substance. Molar mass is a fixed property of a substance regardless of the temperature at which it is measured. Temperature typically affects the physical state and behavior of the substance, but not its molar mass.
What is an intensitive property?
An intensive property is a physical property of a system that does not depend on the quantity of the substance present. Examples include temperature, pressure, and density. In contrast, extensive properties, such as volume and mass, do depend on the amount of the substance.
What properties of a substance does not change when the amount of the substance changes 1 mass 2 volume 3 temperature?
The mass of a substance does not change when the amount of the substance changes. The temperature of a substance does not change when the amount of the substance changes. However, the volume of a substance may change when the amount of the substance changes, depending on the conditions.
Does the density of a substance depend on mass and volume?
yes, to find the density, you do mass divided by volume
