What will an object that is warmer then its surroundings do?
In that case, heat energy will tend to flow from that object to its surroundings.
Campfires transfer energy as heat to their surroundings by what method?
Convection and Radiation
What is it called when a substance releases energy to its surroundings?
There are two ways that a substance ( called the System ) may release energy to the Surroundings :( 1 ) Heat may be released by heat transfer from the System to the Surroundings. Heat transfer from the System to the Surroundings requires the System temperature to exceed the temperature of the Surroundings and the presence of one or more heat transfer modes ( conduction, convection, and/or radiation.( 2 ) Work done by the System of on the Surroundings corresponding to a force moving through a distance, such as when the substance expands. Substance confined to a cylinder with a piston may expand, doing work on the Surroundings.
Where is the heat thermal energy from the balloon and it's surroundings going?
The heat from a hot air balloon is released in the environment.
Why is there a need to reduce the loss of heat to the surroundings?
Basically, heat is a form of energy so depending on the context there will be slightly different answers. But in the case of trying to find out how much energy is produced by something, for example methane, when it combusts it produces heat energy, and some of that heat energy is lost to the surroundings, so when you then try to find the final figure for it's energy production, it will be lower and also wrong.

Heat is?
Heat is a form of energy resulting from the temperature difference between a system and its surroundings.
Where does energy come from an endothermic reaction?
From the surroundings. From Wikipedia: "...a process or reaction in which the system absorbs energy from its surroundings in the form of (usually, but not always) heat."
Energy is what when work is done?
Usually it dissipates into heat released into the surroundings.
Campfires transfer energy as heat to their surroundings by what method?
Convection and Radiation
Is heat the sum of kinetic energy then what is temperature?
Temperature is the average kinetic energy of atoms as they move in and out of a system and its surroundings. Heat is the kenetic energy that is transferred.
A process or reaction which releases heat to the surroundings is said to be?
Reactions that require energy in the form of heat are called endothermic.
What term refers to a chemical reaction that absorbs heat energy?
Absorbing energy from the surroundings is endothermic. (The opposite - releasing energy to the surroundings - is exothermic).
Why do endothermic reactions absorb heat?
a process or reaction in which the system absorbs energy from the surroundings in the form of heat.
What happnes to energy when work is done?
Usually it dissipates into heat released into the surroundings.
How energy lost during transmission?
It's lost as thermal heat to surroundings.
What is an ednothermic change?
An endothermic change is a process that removes heat energy from its surroundings.
