As a block of ice melts, its weight changes from 1 lb to Ib. This change. The ice melts at a constant rate. At what rate does the weight of the ice change? Show your work.

No temperature change occurs from heat transfer if ice melts and becomes liquid ... The given figure shows a vertically downward, knife-shaped ice piece, with water ... They are latent, or hidden, because in phase changes, energy enters or ... of the liquid water rises, absorbing heat at a new constant rate of 1.00 cal/g⋅ ºC.

Step-by-step explanation:

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
