Answer:
C.The particles in the hot water will slow down, while the particles in the cold water will speed up
Explanation:
Heat causes changes in the molecules of substances when applied to them. The molecules of water, as a case study used in this question, when heated has an increased kinetic energy which causes its particles to move faster i.e. speed up. Also, when water is freezed or cold, it's particles move slower i.e. slow down due to decreased kinetic energy.
Hence, when a hot glass of water and a cold glass of water are placed on a kitchen table for 1 hour, they don't remain in their respective thermal state.
- The hot water (with an increased movement of molecules) begin to cool down, hence, its particles slows down as it gets cold or less hot.
- Likewise, the cold water (with a decreased movement of molecules) begins to get warmer, hence, it particles speedens up as it gets warmer.
Therefore, The particles in the hot water will slow down, while the particles in the cold water will speed up
You need to put a question in order for people to answer
Answer:
Final volume of the gas is 4.837mL
Explanation:
Initial volume (V1) = 350mL = 0.35L
Initial temperature (T1) = 0°C = (0 + 273.15)k = 273.15k
Initial pressure (P1) = 1.0atm
Final volume (V2) = ?
Final temperature (T2) = 10°C = (10 + 273.15)k = 283.15K
Final pressure (P2) = 75atm
To solve this question, we'll have to use combined gas equation which is the combination of all gas law I.e Charle's laws, Boyle's law, Pressure law etc.
According to combined gas equation,
(P1 × V1) / T1 = (P2 × V2) / T2
Make V2 the subject of formula,
V2 = (P1 × V1 × T2) / (P2 × T1)
V2 = (1.0 × 0.35 × 283.15) / (75 × 273.15)
V2 = 99.1025 / 20,486.25
V2 = 0.004837L
V2 = 4.837mL
The final volume of the gas is 4.837mL
Answer:
A hypothesis is either a suggested explanation for an observable phenomenon, or a reasoned prediction of a possible causal correlation among multiple phenomena. In science, a theory is a tested, well-substantiated, unifying explanation for a set of verified, proven factors.
