Question

use the following information to answer question 6.

using a ramp, students test the effect of temperature on the viscosity of two 30 ml samples of corn syrup. each sample is heated to a different temperature. both samples are poured from the top of a 45 cm ramp. the time it takes for the corn syrup samples to flow to the bottom is recorded in the table below.

\

$$\begin{tabular}{|c|c|c|} \\hline & temperature (\\(^{\\circ}\\text{c}\\)) & time (s) \\\\ \\hline sample a & 22.0 & 55 \\\\ \\hline sample b & 46.2 & 32 \\\\ \\hline \\end{tabular}$$

1. sample b has a \\(i\\) viscosity than sample a, which causes the particles of corn syrup in sample b to flow \\(ii\\).

the statement above is best completed by the answers in row:

\

$$\begin{tabular}{|c|c|c|} \\hline row & \\(i\\) & \\(ii\\) \\\\ \\hline a. & lower & slower \\\\ \\hline b. & lower & faster \\\\ \\hline c. & higher & slower \\\\ \\hline d. & higher & faster \\\\ \\hline \\end{tabular}$$
