The correct answer is D. Energy that flows from a hot mug of tea to a cold hand
Explanation:
Heat refers to a type of energy that is the result of the motion of atoms in the matter; additionally, heat differs from other types of energy because this flows between objects or surfaces, usually as energy or heat flow from a hot surface to a colder one. Besides this, heat transference can occur due to conduction that involves direct contact of surfaces, radiation that involves electromagnetic waves or convection that involves movement of particles in liquids or gases. Thus, the statement that describes heat is " Energy that flows from a hot mug of tea to a cold hand" because this shows the flow of heat or energy from a hot surface to a colder one.
The last option, "Energy that flows from a hot mug of tea to a cold hand." Hope this helps!
(This is because heat is the transfer of energy that you can well, feel. In simple terms. For this question and other like it you can do process of elimination because the only one that involves heat, is the last option.)
Hello sir, The answer that you are looking for is fluorine. Fluorine is the most electronegative atom. I am also sorry for calling you sir. I didn't know you were a woman.
Answer: O potássio possui apenas um elétron de valência. ... Considerando que o cálcio possui dois elétrons de valência, requer mais energia para a remoção de um elétron de valência. Devido a esse potássio, é mais reativo que o cálcio.
