A 25.0 g block of copper (specific heat capacity 0.380 J/g.°C) at 88.0 °C is placed into 500.0 g of water initially at 20.0 °C. What is the
change in temperature (in °C) of the copper block? (The specific heat
capacity of water is 4.184 J/g.°C).

Density and pressure

For a cell to pass the g2 checkpoint, there must be accurate and complete dna replication. there must also be a maturation promoting factor which to maintain the metaphase ii stage arrest . the g2 also known as 2nd gap  phase, is usually responsible for continued growth and preparation for cell division. 

The rules are different for multiplication and addition, but the least precise value always restricts the answer. first do the multiplication (as per standard order of operations): 24.6681 × 2.38 ≈ 58.7 since 2.38 has the fewest significant figures, it is considered the lease precise value then do the addition: 58.7 + 332.58 ≈ 391.3 since 58.7 has fewest figures right of decimal it is considered least precise. so final answer: 391.3 with four significant figures.
