Why metal gets much hotter than a bucket of water in the sun?
Metal gets much hotter than a bucket of water in the sun primarily due to its higher thermal conductivity and specific heat capacity. Metals efficiently absorb and retain heat energy from sunlight, causing their temperature to rise quickly. In contrast, water has a high specific heat capacity, meaning it requires more energy to raise its temperature, leading to slower warming. Additionally, metals tend to have lower emissivity, which means they do not radiate heat as effectively as water, allowing them to remain hotter in direct sunlight.
From the graph can you generalize that the higher the layer of the athmosphere (that is closer to the sun) hotter temperature why or why not?
Based on the graph, can you generalize that the higher the layer of the atmosphere (that is closer to the sun), the hotter the temperature? Why or why not
The bigger the hotter the star the what?
The bigger and hotter a star is, the shorter its lifespan will be. This is because higher temperatures cause stars to burn through their fuel more quickly, leading to a faster depletion of their energy source and a shorter overall existence.
Why is a lightning bolt hotter then the sun?
A lightning bolt is hotter than the sun in a small area due to the rapid discharge of electrical energy, which results in the localized heating of the air. However, the total energy output of the sun is much higher and its overall temperature is significantly hotter than a lightning bolt.
Why does temperature happen within things?
Temperature is a measure of the average kinetic energy of the particles within a substance. When these particles move faster, they have higher kinetic energy and therefore a higher temperature. This movement is a result of the energy transfer between particles in response to differences in temperature, causing heat to flow from hotter regions to cooler regions.
Do hotter objects radiate more total energy per unit area than colder objects?
Yes, hotter objects radiate more total energy per unit area than colder objects. This is described by Stefan-Boltzmann's law, which states that the total energy emitted by a blackbody is proportional to the fourth power of its temperature.
Can one object be hotter be hotter than another if they have the same temperature?
No, two objects with the same temperature will have the same level of thermal energy, so they cannot differ in temperature. Temperature is a measure of average kinetic energy of particles in a substance, so if temperatures are equal, the objects are equally hot.
Does thermal energy flow from cooler to hotter objects?
No, thermal energy flows from hotter objects to cooler objects as heat always moves from areas of higher temperature to lower temperature, seeking equilibrium.
What causes radiation to be released from stars?
They're hotter than the background (about 5 degrees Kelvin) , they must radiate.
Is the lower hotter for Celsius?
No, in Celsius temperature scale, lower temperatures are colder and higher temperatures are hotter.

The energy transferred from a hotter object to a cooler one?
The law says that energy can neither be created nor be destroyed. It can only be transferred from one form to another.... And energy always from higher potential to lower potential... Since hotter object is at high potential and cooler object at lower potential, the heat energy will flow from hotter to cooler object.
What is the energy transferred from a hotter object to a cooler one referred to?
The energy transferred from a hotter object to a cooler one is referred to as heat transfer. Heat transfer occurs due to the temperature difference between the objects and always flows from higher temperature to lower temperature to reach thermal equilibrium.
Do all things radiate?
Yes, all objects radiate some heat BUT the hotter the object, the more heat it radiates!! radiation its self is not hot but when it is absorbed by an object its particles in the object move more rapidly thus heating it
What is the energy transferred from a hotter object to a cooler one is referred to as what?
The energy transferred from a hotter object to a cooler one is referred to as heat. Heat flows from the object at a higher temperature to the object at a lower temperature until thermal equilibrium is reached.
On the Celsius scale if it is low does that mean it is hotter?
No, higher numbers are hotter.
What is energy transfered from a hotter object to a colder object called?
The process of energy transfer from a hotter object to a colder object is called heat transfer. Heat always flows from a region of higher temperature to a region of lower temperature in order to achieve thermal equilibrium.
