What 3 things can happen to radiated heat when it reaches an object?
When radiated heat reaches an object, it can be absorbed, reflected, or transmitted through the object. Absorption occurs when the object takes in the heat energy, reflection happens when the heat is bounced off the object's surface, and transmission occurs when the heat passes through the object.
Heat can never flow from what?
Heat can never flow from a colder object to a hotter object according to the Second Law of Thermodynamics. Heat naturally flows from a hotter object to a colder object in order to equalize their temperatures.
What For heat to transfer from object to object by physical contact what has to happen?
In order for heat to transfer from one object to another by physical contact, the objects must be at different temperatures. Heat naturally flows from the object with higher temperature to the object with lower temperature until thermal equilibrium is reached.
How do you determine the specific heat capacity of an object by method of cooling?
To determine the specific heat capacity of an object by the cooling method, you would first heat the object to a known temperature and then immerse it in a known volume of water at a lower temperature. By monitoring the temperature change of the water and the object over time, you can calculate the specific heat capacity of the object using the formula q = mcΔT.
when a cold object is touched state whether the heat energy flows from the person's hand to the object or the object to the person's hand and why is it so?
When a cold object is touched, heat energy flows from the person's hand to the object. This is because heat always flows from the higher temperature (hand) to the lower temperature (object) in order to reach equilibrium. The sensation of coldness is due to the loss of heat energy from the hand to the colder object.

How do ratdiation heat things?
heat radiation gives an object energy and it begins to vibrate (molecular level) which heats the object. Its like a person jumping around will heat up, works the same with particles in an object

Why do things change temperature?
Things change temperature because of the transfer of heat energy. Heat energy can be transferred from one object to another through conduction, convection, or radiation, causing the object's temperature to increase or decrease.

The sensation of coldness is due to the loss of heat energy from the hand to the colder object.
How to calculate heat dissipation in a system?
To calculate heat dissipation in a system, you can use the formula Q mcT, where Q is the heat energy, m is the mass of the object, c is the specific heat capacity of the material, and T is the change in temperature. This formula helps determine how much heat is being transferred and dissipated in the system.
Why is a measured amount of water needed to determine the spicific heat of a metal object?
A measured amount of water is used in determining the specific heat of a metal object because water has a well-defined specific heat capacity (1 calorie/gram °C) and is readily available. By measuring the temperature change of a known mass of water when a metal object is immersed in it, and knowing the specific heat of water, we can calculate the specific heat of the metal object.
How does heat move from warmer things to cooler things?
Heat moves from warmer things to cooler things through a process called conduction, where the kinetic energy of the molecules in the warmer object is transferred to the molecules in the cooler object through direct contact. The heat transfer continues until both objects reach thermal equilibrium, with the same average kinetic energy among their molecules.
How does light heat up things?
Light transfers its energy to an object by being absorbed and converted into heat. When light waves strike an object, the energy is converted into thermal energy, causing the object's molecules to vibrate and generate heat. The more light energy absorbed by an object, the hotter it becomes.
The amount of thermal energy stored in a object depends on?
The amount of thermal energy stored in an object depends on its mass, temperature, and specific heat capacity. The formula to calculate thermal energy is Q = mcΔT, where Q represents thermal energy, m is mass, c is specific heat capacity, and ΔT is the change in temperature.
