Specific Heat Problems
Q = mCpT Units are Joules (J)
1. How much heat is needed to raise the temperature of 400 grams of water from 0.0 C
to 15 C the Specific Heat of water is 4.186 J/g*C?
A(Asking) – Q =?
G(Giiven) – m=400g, Cp = 4.186 J/g* C, T = 15.0 C- 0.0 C =15 C
E(Equation) – Q= mCpT
S(Substitute & Solve) – Q = (400 g)(4.186 J)(15 C) =

Classify the following soils according to the uscs classification system. provide appropriate uscs designations. a) this sample of well-graded gravel with sand was obtained from a large earthen dam in vancouver, canada. the sample has 73% fine to coarse sub-angular gravel, 25% fine to coarse sub-angular sand and 2% fines. the maximum size of the particles is 75 mm. the coefficient of curvature is 2.7, while the uniformity coefficient is 12.4. b) this dark brown and wet soil with a “strong organic odor” has 100% passing the no. 200 sieve. the liquid limit of the material is 32% when not dried and is 21% when oven-dried. the plastic index is 21% when not dried. c) this sand has 61% predominantly fine sand, 23% silty fines, and 16% fine sub-rounded gravel size. the maximum size is 20 mm. the liquid limit is 33% and the plastic limit is 27%. d) this soil has 74% fine to coarse sub-angular reddish sand and 26% organic and silty dark brown fines. the liquid limit is 37% when not dried and is 26% when oven dried. the plastic index is 6% when not dried.
