What is the specific heat of copper if a 105 g sample absorbs 15200 joules and the change in temperature is 377 0C ? (Draw a temperature time graph)

Answer : The specific heat of copper is,

Explanation :

Formula used :

where,

q = heat absorb = 15200 J

m = mass of sample = 105 g

c = specific heat capacity of copper = ?

= change in temperature =

Now put all the given values in the above formula, we get:

Therefore, the specific heat of copper is,

air

in a tire you fill a tire with air

then a couple days later you check the air pressure in the tire

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
