A) 0

question 61

Multiple Choice

A certain material is in a room at 27°C. If the absolute temperature (K) of the material is tripled, its resistance quadruples. (Water freezes at 273 K.) What is the value for $\alpha$ , the temperature coefficient of resistivity?

• A) 0.0050 (°C) ^{- 1}
• B) 0.0025 (°C) ^{- 1}
• C) 1 (°C) ^{- 1}
• D) 3 (°C) ^{- 1}
