Answer:
577g
Explanation:
Given parameters:
Temperature change = 5.9°C
Amount of heat lost = 427J
Unknown:
Mass of the block = ?
Solution:
The heat capacity of a body is the amount of heat required to change the temperature of that body by 1°C.
H = m c Ф
H is the heat capacity
m is the mass of the block
c is the specific heat capacity
Ф is the temperature change
Specific heat capacity of lead is 0.126J/g°C
m = H / m Ф
m = = 577g
Mass of the lead block is 577g
Answer:
The value is
Explanation:
From the question we are told that
The volume of liquid nitrogen is
The density of nitrogen at gaseous form is = The dry air at sea level
Generally the density of nitrogen at liquid form is
And this is mathematically represented as
=>
Now the density of gaseous nitrogen is
=>
Given that the mass is constant
=>
