A student wants to measure the specific heat capacity of an unknown metal. They first measure the mass of the metal sample and find that the metal sample is 128.432g. They heat the metal in a hot water bath until its initial temperature is 98.3 degrees Celsius. They then poured the metal into a calorimeter containing 41.251g of water at an initial temperature of 22.5 degrees Celsius. After thermal equilibrium was reached the temperature was 36.3 degrees Celsius

The formula $V(t) = 300(1 - e^{-0.025t})^3$ models the relationship between the size of a certain type of tumor and the amount of time that it has been growing, where $t$ is in months and $V(t)$ is measured in cubic centimeters. Calculate the rate of change of tumor volume at 190 months. Round to the nearest thousandth.

Chapter 3-Hydraulic System Fundamentals 85 T F 10. Hydraulic fluids with a high VI number change drastically as the temperature changes. T F 11. Hydraulic fluid is typically pure without any extra additives. T F 12. In a hydraulic system, the pressure in the system drops for a short period when several components activate at the same time. T F 13. A fluid with high viscosity is thin and flows easily. T F 14. A schematic diagram is also called a graphic diagram. T F 15. The viscosity of a specific fluid is always determined under conditions in the field. T F 16. Hydraulic power units are sometimes referred to as pumping units. T F 17. Liquids are easily compressed. T F 18. Fluids flow because they move from low-pressure areas to high-pressure areas. T F 19. In a hydraulic system, the bladder design is the most commonly used gas-charged accumulator. T F 20. There are 128 cu in. in one gallon. T F 21. Self-contained hydraulic power units are typically large and stationary. T F 22.
