Temperature increases with more mass of a metal because larger masses can store more thermal energy. When heat is applied, more mass means a greater quantity of atoms or molecules are absorbing that energy, leading to a rise in temperature. Additionally, the specific heat capacity of the metal influences how much temperature increases for a given amount of heat added; metals with lower specific heat capacities will show a more significant temperature increase with added mass.

What happens to the volume of a metal ball when it is heated?
When a metal ball is heated, its volume increases due to thermal expansion. As the temperature rises, the metal's atoms vibrate more vigorously and tend to occupy more space, causing the ball to expand. This increase in volume occurs uniformly, affecting the entire structure of the ball. However, the mass of the metal remains unchanged during this process.
How would an increase in mass affect the basic properties of a star?
An increase in mass would lead to an increase in the temperature and pressure at the core of the star, leading to a faster rate of nuclear fusion reactions and a brighter luminosity. It would also affect the star's lifespan, as higher mass stars burn out more quickly than lower mass stars. Additionally, higher mass stars are more likely to end their life cycles in supernova explosions.
What would increase the pressure inside a tank of helium gas?
You have several options, including:Increase the temperature of the gas, keeping the volume and mass of gas constant.Decrease the volume of the tank (e.g. with a piston), keeping the temperature and mass of gas constant.Add more gas to the tank, keeping the volume and temperature constant.
A sample of an unknown metal has a mass of 58.932 g It has been heated to 101.00 C then dropped quickly into 45.20 ml of pure water?
To determine the metal's specific heat capacity, we need more information such as the initial temperature of the metal, the final equilibrium temperature after it's in contact with water, and the temperature change of the water. With this data, we can use the equation q = mcΔT, where q is the heat transferred, m is the mass of the metal, c is the specific heat capacity, and ΔT is the change in temperature.
When the same amount of heat is applied to a given mass of water or that same total mass of water and steel together which will heat up to a higher temperature?
When the same amount of heat is applied to a given mass of water and an equal mass of water combined with steel, the water will heat up to a higher temperature. This is because water has a higher specific heat capacity than steel, meaning it requires more energy to increase its temperature. Consequently, when the same amount of heat is distributed, the water will experience a greater temperature increase compared to the water-steel combination, where some heat is absorbed by the steel, resulting in a lower overall temperature increase for the water.
What three factors affect thermal energy?
raising of object temperature, the mass, specific heat
Does increase in hardness of a metal increases its weight?
Increasing the hardness of a metal does not directly increase its weight. Hardness is a measure of a metal's resistance to deformation, while weight is determined by its mass. However, changes in the metal's composition or structure to increase hardness may affect its density, which could in turn impact its weight.
What happens to the volume of a metal ball when it is heated?
When a metal ball is heated, its volume increases due to thermal expansion.

Why when you pump in more air into the float it does not increase in mass?
It depends on the strength of the float's walls, and what the float actually is? Pumping more air into a balloon will increase its mass. Pump air into a metal tank, and while the pressure inside will increase, the mass of the metal tank would remain the same.
What will happen if the temperature of a metal pan is increased?
As the temperature of a metal pan increases, the metal atoms will gain kinetic energy and vibrate more rapidly. This will cause the pan to expand slightly. If the temperature increase is too high, the metal may eventually reach its melting point and start to melt.
How would an increase in mass affect the basic properties of a star?
An increase in mass would lead to an increase in the temperature and pressure at the core of the star, leading to a faster rate of nuclear fusion reactions and a brighter luminosity. It would also affect the star's lifespan, as higher mass stars burn out more quickly than lower mass stars. Additionally, higher mass stars are more likely to end their life cycles in supernova explosions.
How does metal get hot?
When metal is exposed to a heat source, such as fire or electricity, the atoms within the metal start vibrating more rapidly, leading to an increase in temperature. This increase in temperature causes the metal to heat up and potentially reach a point where it begins to emit light in the form of glowing or melting.
Why as load increase the condenser temperature will also increase?
Because the more the load the more the temperature.
When temperature increases does density increase or decrease?
An increase in temperature usually causes an increase in volume. Since the mass doesn't change, density decreases. tt
How does mass affect thermal energy?
The thermal energy of any substance is the product of its specific heat and the temperature difference between it and the surroundings. So if you increase the temperature you directly increase the thermal energy, in proportion to the difference between its temperature and ambient temperature.
What happens to gravity when you increase the mass of objects?
More mass --> more gravity.
How is the thermal expansion works?
as the temperature increases the atoms in a metal gain energy so the KE of the atoms increase this increase their movement for this it requires more space so it expans to increase the gap between the atoms or molecules
