he density of liquid oxygen at its boiling point is 1.14 kg/L , and its heat of vaporization is 213 kJ/kg .How much energy in joules would be absorbed by 3.0 L of liquid oxygen as it vaporized?Express your answer to two significant figures and include the appropriate units.

A student is using a calorimeter to determine the specific heat of a metallic sample. She measures out 128.1 grams of her metal and heats it to 79.6 degrees Celsius. Then, she puts the sample into a calorimeter containing 11.47 grams of water at 45.7 degrees Celsius. She measures the temperature of the water in the calorimeter until the number stops changing, then records the final temperature to be 71.4 degrees Celsius. What is the specific heat of the metal? Please answer to three digits after the decimal point.

It takes 2.16 J of heat to raise the temperature of Object A by 1 °C, and 4.64 J to raise the temperature of Object B by 1 °C. Suppose A and B are brought into contact. A is initially hotter. A is seen to cool down by 6.9 °C. How would you calculate the rise in temperature of B? Set the math up. But don't do any of it. Just leave your answer as a math expression. Also, be sure your answer includes all the correct unit symbols. change in temperature of B = 0 Continue OO X 9 0.0 3 wevee muuiầw Hill LLC. All Rights Reserved.

Stainless steel accessories in cars are usually plated with chromium to give them a shiny surface and to prevent rusting. When 5.00 g of chromium at 23 degrees Celsius absorbs 14.9 calories of heat, the temperature increases to 50.8 degrees Celsius. What is the specific heat of chromium (in cal/g degrees celsius)?
