Explanation:
When a brick is heated to a temperature between 20°C and 150°C, it loses most of the water added to the clay during the preparation phase. ... When the temperature starts to rise over 600°C, chemical changes begin to occur in the clay which give the brick colour, hardness and durability.
Answer:
5.4 atm
Explanation:
P•V/T = P'•V'/T'
2.4•2.2/290 = P'•2/296
5.28/290 = P'/296 Multiply both sides by 296
1562.88/290 = P'
I'm = 5.4 atm
