Density will increase. The metal contracts (gets smaller) but will still weigh the same thing.
What else can I help you with?
What happens to a floating object in a river when air pressure and density decreases Does it rise in floating level sink or stay the same?
If air pressure and density decrease, the buoyant force pushing up on the object will decrease as well, causing the object to sink. This is because the weight of the object becomes greater than the buoyant force acting on it, leading it to no longer float at the same level.
What changes when the mass of an object increases while volume stays the same?
Assuming mass does not also increase, then density decreases if volume increases. For example, let's say Mass= 100 and Volume= 50 Density would = 2 Now, lets increase the volume. Mass would still = 100, and let's increase the volume to 75. Density would then equal 1.333... 2 is greater than 1.333.... so yes, density decreases as volume increases.
How do object change temperature?
Objects change temperature through the transfer of heat energy. This can occur through conduction, convection, or radiation. When an object gains heat energy, its temperature increases, and when it loses heat energy, its temperature decreases.
How does temperature change between the surface and center?
Temperature generally decreases as you move from the surface of an object towards its center. This is because at the surface, the object is exposed to external factors like sunlight or other heat sources. As you move towards the center, there is less exposure to external influences, leading to a decrease in temperature.
If two objects have the same density does it float are sink?
The previous answer was incorrect. Whether or not it will float has nothing to do with density being more or less than one. If an object is of the same density as the fluid, it will float just beneath the surface of the fluid, because the buoyant force is exactly equal to the object's weight. (which makes sense, because buoyant force is equal to the weight of the volume of fluid displaced by the object, and the densities are equal. Remember, density=m/V!) This results in a net force of zero (buoyant force pushes up with exactly the same magnitude as the weight vector, which points down, so they cancel out), meaning there is nothing to cause the object to sink or float.
What happens to an object's density when it heats up and expands?
The density decreases.
What happens to radiation from an object as its temperature increases?
radiation from object decreases as the temperature rises
When the temperature of an object decreases what happens to the molecules?
In every liquid (with the exception of water) the molecules, when the temperature decreases, contract.
What happens to the thermal energy of an object as temperature decreases as it increases?
As the temperature of an object decreases, its thermal energy also decreases because the particles within the object have less kinetic energy. Conversely, as the temperature increases, the thermal energy of the object increases as the particles move more rapidly, resulting in higher kinetic energy.
How does raising the temperature of an object affect its density?
Increasing the temperature of an object generally decreases its density. This is because as the temperature rises, the particles within the object gain more kinetic energy and spread out, causing the object to expand. Conversely, lowering the temperature would usually increase the density of the object as the particles lose kinetic energy and move closer together.
What happens to an object's density when it heats up?
When an object heats up, its density typically decreases. This is because as the object's temperature increases, its particles gain energy and move more quickly, causing the object to expand. As a result, the same amount of mass now occupies a larger volume, leading to a decrease in density.
What happens to density as an object contracts?
As an object contracts, its volume decreases while its mass remains constant. This results in an increase in the density of the object since density is defined as mass divided by volume.
When air transfers energy to a cooler object what happens to air temperature?
it decreases.
When an object's volume is made the smaller but it's mass remains the same what happens to its density?
If the volume of an object decreases but its mass remains the same, the density of the object will increase. Density is calculated as mass divided by volume, so if the volume decreases while the mass stays constant, the overall density will be higher.
What heat flows out of an object what happens to the temperature?
When heat flows out of an object, the temperature of the object decreases because heat is a form of energy that moves from hot to cold. As heat is lost, the object loses internal energy and its particles slow down, resulting in a lower temperature.
What is negative temperature cofficient?
A negative temperature coefficient indicates that the dependent variable, the variable of interest increases when the temperature decreases and conversely. This could, for example, be the density of an object (excluding water at 0 - 4 deg C). As the temperature goes up the volume increases so the density decreases.
What happens to thermal energy when temperature decreases?
When the temperature decreases, thermal energy decreases as well. This means that the particles in the object have less kinetic energy and move more slowly. If the temperature continues to decrease, the object may eventually reach a point where all motion stops and it reaches absolute zero temperature.
