If you start with 146 g of water at 47◦C, how much heat must you add to convert all the liquid into vapor at 100◦C? Assume no heat is lost to the surroundings. Answer in units of kJ.

A coffee cup calorimeter contains 100.0 g of water at 10.0 ◦C. A 72.4 g sample of iron is heated to 100 ◦C and dropped into the calorimeter. Assuming there is no heat lost to the coffee cup, calculate the final temperature of the system. The specific heat...

Polygon MNOPQ is dilated by a scale factor of 0.8 with the origin as the center of dilation, resulting in the image M′N′O′P′Q′. The coordinates of point M are (2, 4), and the coordinates of point N are (3, 5).The slope of MN is
