how many grams of water (is=4.184 J/g degrees celcius) will release 1367 J of heat when cooled to 45.2 degrees celcius to 36.2 degrees Celsius
С = 4.184 J/(g*C) delta T = 9 C for m = 1 and delta t=9 it is 4.184*9=37.656 j for m=x and delta t =9 it is 1367/37.656 =...

A 35.0 g block of copper at 350.0 degrees celcius is added to a beaker containing 525 g of water at 35.0 degrees celcius. What is the final temperature of water?
Let us denote mc - mass of copper = 35 g cc - specific heat capacity of copper = 385 J/(kg*K) tc - temperature of copper = 350 C =...

if the temperature of the helium balloon were increased from 30 celcius to 35 celcius and the volume of the ballon only expanded from 0.47 L to 1.55 L, how much pressure would be inside the ballon?
According to the combined gas law equation:p1V1/T1 = p2V2/T2where p1 - initial pressure, V1 - initial volume, T1 - initial temperature, p2 - final pressure, V2 - final volume, T2 - final temperature.From here:p2/p1 = V1T2/V2T1As 30°C =...

Calculate the amount of heat released when one bottle (250g) of water is cooled from 30 degrees celcius to 25 degrees celciuis. The specific heat of water is (-4.186J/g degress celcius-).
Solution:To calculate the amount of heat entering or leaving a system, the equation Q = mcΔT is used.m = mass (in grams)c = specific heat capacity (J/g°C)ΔT = change in...

The heat needed to vaporize a certain amount of liquid. A certain substance A has a boiling point of 78 degrees celcius and substance B has boiling point of 100 degrees celcius
A ‒ boiling point TB = 78 ⁰CB ‒ boiling point TB = 100 ⁰CLiquids are called condensed phases because their particles are packed in close proximity to one another....
