True/False
A hot object has more thermal energy than a similar cold object only because of greater kinetic energy.
answer:true
False
True.
A hot object does indeed have more thermal energy than a similar cold object mainly because of its greater kinetic energy. Kinetic energy refers to the energy associated with the motion of particles within an object. In a hot object, the particles are moving faster and have higher kinetic energy compared to those in a cooler object.
To understand this concept, it is helpful to know that temperature is a measure of the average kinetic energy of particles in an object. So, when an object is hotter, it means that, on average, its particles have more kinetic energy.
To further explain why a hot object has more thermal energy, we can consider the formula for thermal energy:
Thermal energy = mass × specific heat capacity × temperature
In this formula, mass refers to the amount of matter in the object, specific heat capacity is the amount of energy required to raise the temperature of a given mass of a substance, and temperature refers to the average kinetic energy of the particles.
As the temperature of an object increases, its thermal energy increases because the temperature is directly proportional to thermal energy. This means that a hot object will have more thermal energy than a similar cold object, primarily due to the greater average kinetic energy of its particles.
