A pendulum clock loses 12 s a day if the temperature is 40 o C and gains 4s a day if the temperature is 20 o…

1. ${30}^{\mathrm{o}}\mathrm{C};\mathrm{\alpha }=1.85\times {10}^{-3}$ / ${}^{\mathrm{o}}\mathrm{C}$
2. ${55}^{\mathrm{o}}\mathrm{C};\mathrm{\alpha }=1.85\times {10}^{-2}$ / ${}^{\mathrm{o}}\mathrm{C}$
3. ${25}^{\mathrm{o}}\mathrm{C};\mathrm{\alpha }=1.85\times {10}^{-5}$ / ${}^{\mathrm{o}}\mathrm{C}$
4. ${60}^{\mathrm{o}}\mathrm{C};\mathrm{\alpha }=1.85\times {10}^{-4}$ / ${}^{\mathrm{o}}\mathrm{C}$
