Plug in values and find k: First, let's plug in the values we know into the formula to find k. We have Ta=325, T0=70, T=116, and t=2.5. So, 116=325+(70−325)e(−k∗2.5).
Simplify the equation: Now, let's simplify the equation. We get 116=325−255e−k×2.5.
Isolate the exponential term: Subtract 325 from both sides to isolate the exponential term. We get −209=−255e−k⋅2.5.
Solve for e(−k∗2.5): Divide both sides by −255 to solve for e(−k∗2.5). We get e(−k∗2.5)=255209.
Take natural logarithm: Now, take the natural logarithm of both sides to solve for −k×2.5. We get −k×2.5=ln(255209).
Solve for k: Divide both sides by −2.5 to solve for k. We get k=−ln(255209)/2.5.
Calculate the value of k: Calculate the value of k. k≈−ln(255209)/2.5≈0.231.
