Are molecules in cool substances closer together than in hot substances?
Yes, in general, molecules in cool substances are closer together than in hot substances. As substances cool down, their molecules lose energy and move more slowly, causing them to come closer together and form a more compact arrangement. Conversely, in hot substances, molecules have more energy and move rapidly, leading to increased distance between them.
What are the oxidation rules that govern chemical reactions involving the transformation of substances?
Oxidation rules determine how substances change in chemical reactions. These rules help identify which atoms lose or gain electrons, leading to the formation of new substances.
Why can lithium gain and lose electrons?
Lithium can gain and lose electrons because it has three electrons in its outermost energy level. It can lose one electron to achieve a stable configuration like a noble gas, or gain seven electrons to complete its outer shell. This ability allows lithium to form different ions with different charges.
Does a substance gain o lose thermal energy when it evaporates?
A substance gains thermal energy when it evaporates, as energy is required to break the intermolecular forces holding the molecules together and allow them to escape into the gaseous phase.
Does a substance gain or lose energy during evaporation?
During evaporation, a substance gains energy from its surroundings to break the intermolecular bonds and escape as a gas. This results in a cooling effect on the surroundings as energy is absorbed by the substance.
When do most substances lose or gain energy?
Most substances lose or gain energy when their temperature changes.
When compounds gain electrons they lose or gain energy?
Lose
What happens to the temperature of substance while it is changing state?
It can lose or gain energy or it forms the attractions between particles.
What happens to temperature of a substance while it is changing state?
It can lose or gain energy or it forms the attractions between particles.
What happens to the substances involved in a chemical change?
Several different outcomes can occur to reacting substances in chemical reactions. An atom will typically either lose or gain electrons, which will make it negatively or positively charged.
What does not gain or lose mass?
a closed system will not gain or lose mass
What happens when oceans gain and lose heat slowly?
Nothing Happens
Does gas lose or gain thermal energy in condensation?
When condensation occurs, it is a gain thermal energy.
What happens to the energy inside the rock as metamorphic rock becomes igneous rock?
Metamorphic rocks gain enegry as they are melted by magma and then lose energy as they cool into igneous rocks.
What happens when the temperature of a substance decreases significantly A. Most substances will expand. B. Most substances will gain atoms. C. Most substances will contract. D. Most substances will d?
C. Most substances will contract. When the temperature of a substance decreases significantly, its particles lose kinetic energy, causing them to move closer together. This results in a decrease in volume, known as contraction.
How do substances move from one state to another?
Substances can change states through processes such as melting, freezing, evaporation, condensation, or sublimation. These changes occur when the temperature or pressure of the substance is altered, causing the particles to either gain or lose energy and rearrange themselves into a different state.
When condensation occurs does does lose or gain thermal energy?
its loses thermal energy...
