Q: How is thermal energy transferred in every-day, real life situations, such as holding a warm cup? Read this paragraph and choose the correct option from the provided answers: A: Thermal energy is transferred by conduction from the hot iron to the shirt, from the hot cup to the hand holding it, from the flame of the camp stove to the bottom of the pot as well as from the bottom of the pot to the food inside, and from the feet to the snow. The shirt, hand, pot, food, and snow become warmer because of the transferred energy. Because the feet lose thermal energy, they feel colder. Choices: - decomposition - condensation - oxidation - conduction A:
(Answer)
conduction

Q: The atoms of a compound are held together by what type of bonds? Read this paragraph and choose the correct option from the provided answers: The atoms of a compound are held together by chemical bonds. Chemical bonds form when atoms share electrons. There are different types of chemical bonds, and they vary in how strongly they hold together the atoms of a compound. Two of the strongest types of bonds are covalent and ionic bonds. Covalent bonds form between atoms that have little if any difference in electronegativity, and result when atoms share electrons. Electronegativity is the power of an atom to attract electrons toward itself. Ionic bonds , in contrast, form between atoms that are significantly different in electronegativity. An ion is an atom that has gained or lost at least one electron. Ionic bonds form between ions of opposite charges. Choices: - covalent - mineral - radiation - chemical A:
(Answer)
chemical
