When water at 0.c freezes is heat lost or gained?
As heat is a form of energy, it isn't lost or gained, it's just converted into another form of energy.
What are the factors that can affect how quickly an object's heat is gained or lost through radiation?
The factors include the object's temperature compared to its surroundings, the object's surface area, and the object's emissivity (ability to emit radiation). Objects with higher temperatures, larger surface areas, and higher emissivities will radiate heat more quickly.
Is heat energy gained by liquid equal to the heat energy lost by metal?
Not necessarily. The heat energy gained by the liquid and lost by the metal can be different because different materials have different specific heat capacities, meaning they require different amounts of energy to change temperature.
Does the difference of temperature affect heat loss?
Yes, the greater the difference in temperature between an object and its surroundings, the faster heat will be lost or gained. This is described by the principle of thermal conduction, where heat flows from the higher temperature object to the lower temperature object until thermal equilibrium is reached.
How can one determine the final temperature of a system using the given initial temperatures and heat capacities?
To determine the final temperature of a system, you can use the principle of conservation of energy. This involves calculating the total heat gained or lost by each component in the system based on their initial temperatures and heat capacities. By equating the total heat gained to the total heat lost, you can solve for the final temperature of the system.

Is any energy lost or gained when a flashlight is turned on?
Some energy is changed to heat and lost. The main energy is still be converted to light beam.
Calculate the final temperature when 50 ml of water at 80?
When allowed to stand for long enough, the final temperature will reach room temperature.

Why the temperature of the water at bottom of water fall is different from temperature at the top?
Heat is lost to or gained from the air while falling.
Why is the total her lost by the granite greater than the total heat gained by the room-temperature water?
The total heat lost by the granite is greater than the total heat gained by the room-temperature water because granite has a higher specific heat capacity, allowing it to store and release more thermal energy as it cools. Additionally, the temperature difference between the granite and the water drives a more significant heat transfer, resulting in more heat being lost by the granite. This imbalance accounts for the greater heat loss from the granite compared to the heat gain experienced by the water.
Why is no machine 100 percent eficent?
No machine can be 100% efficient due to factors such as friction, heat loss, and external factors that affect performance. These limitations result in energy being lost or wasted during the operation of the machine, reducing its overall efficiency.
Who gained and who lost out from the changes of the London dockland?
Property developers gained and local people lost out.
What type of energy is produced when objects become hotter?
The flow of heat energy is classifyed under the subject of Enthalphy, and all heat lost or gained is measured in Joules (J).
