Definition Definition Substance that constitutes everything in the universe. Matter consists of atoms, which are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction: solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
(a) Mass of the Calorimeter (two empty cups) in g: 4.0g
(b) Mass of the cold water and the calorimeter in g: 52.5g
(c) Calculated mass of the coldwater in g [(b)-(a)]: 48.5
(d) Temp. of the Cold Water in C: 14c
(e) Temp. of the Hot Water before mixing with the cold in C: 38c
(f) Mass of the Cold & hot water mixed AND the calorimeter in g: 100.6g
(g) Calculated Mass of the Hot water in g [(f)-(b)]: 48.1g
(h) Temperature of the mixed hot & cold water in C: 26c
(i) Calculated Heat Lost by the Hot Water in J (SHOW WORK and answer!!), q=mcDt, (Mass of Hot Water in g)(4.18J/gC)(Mixed Temp - Hot Water Temp): Yes, it should be a negative value!
(j) Calculated Heat Gained by the Cold Water in J (SHOW WORK and answer!!), q=mcDt, (Mass of Cold water in g)(4.18J/gC)(Mixed Temp - Cold Water Temp): Yes, it should be a positive value!
I do understand how to calcualte the heat gained and lost
You are given a hammer a battery, a bulb, wires and switch(a) How could you use them to distinguish between samples of metals and non metals?(b) Assess the usefulness of these tests to distinguish between metals and non-metals
Imagine a container placed in a tub of water, as depicted inthe accompanying diagram. (a) If the contents of the containerare the system and heat is able to flow through thecontainer walls, what qualitative changes will occur in thetemperatures of the system and in its surroundings? From thesystem’s perspective, is the process exothermic or endothermic?(b) If neither the volume nor the pressure of the systemchanges during the process, how is the change in internal energyrelated to the change in enthalpy?
