Visit this density simulation at the link provided and click the "turn fluid into water" button to adjust the density of liquid in the beaker to 1.00 g/mL. Use the water displacement approach to measure the mass and volume of the unknown material (select the green block with question marks). What are the mass and volume of the material?

Who was the first scientist to measure speed as distance over time?

Two kilograms of air within a piston–cylinder assembly executes a carnot power cycle with maximum and minimum temperatures of 800 k and 300 k, respectively. the heat transfer to the air during the isothermal expansion is 60 kj. at the end of the isothermal expansion the volume is 0.4 m3. assume the ideal gas model for the air. determine the thermal efficiency, the volume at the beginning of the isothermal expansion, in m3, and the work during the adiabatic expansion, in kj.
