Explain how a flying piece of wood that only weighs 15 pounds could turn into a flying missile in a tornado that could cause a tremendous amount
of damage. What would happen if the piece of wood weiged 30 pounds or was a
more massive object like a piece of steel? How would the force exerted on a home
be affected by a flying object with more mass?

When 13.3 g koh is dissolved in 102.7 g of water in a coffee-cup calorimeter, the temperature rises from 21.4 °c to 31.53 °c. what is the enthalpy change per gram of koh (j/g) dissolved in the water? * take the density of water as 1.00 g/ml. * assume that the solution has a specific heat capacity of 4.18 j/g*k. enter to 1 decimal place. do not forget the appropriate sign /(+). canvas may auto-delete the (+) sign
