Which statement is correct? when a positively charged atom looses an electron to a positively charged atom, two neutral atoms are created. when a neutral atom looses an electron to another neutral atom, two charged atoms are created. when a neutral atom looses an electron to a positively charged atom, both atoms become neutral. when charged atoms lose electrons they will become positively charged atoms.

Which is not a characteristic of a heat pump? a. it is used in air conditioners. b. it uses a refrigerant. c. it requires no work. d. it reverses the normal flow of thermal energy.

What is the role of lenses in microscopy?

Beryl states that insulation with the smallest possible thermal conductivity is best to keep a house warm in winter, but worst for keeping a house cool in summer. sapphire insists the reverse is true: low thermal conductivity is good in the summer, but bad in the winter. which one, if either is correct? a. beryl, because low thermal conductivity results in low heat transfer. b. beryl, because low thermal conductivity results in high heat transfer. d. sapphire, because low thermal conductivity results in high heat transfer. e. neither, because low heat transfer is desirable both in summer and in winter.
