Should You Adjust Your Thermostat When Leaving Home for Short Periods?

AI Thread Summary
When leaving home for a short period, such as half an hour, it is generally more energy-efficient to leave the thermostat at the same temperature rather than adjusting it. Lowering the thermostat may lead to increased energy use when reheating the space upon return. Some discussions suggest that maintaining a consistent temperature can save fuel and energy. Additionally, closing blinds can help retain heat in the home. Overall, keeping the thermostat steady is often recommended for short absences.

My question is as follows:
If you wsh to save fuel on a cold day. and you're going to leave your house for a half hour or so, should you turn the thermostat down a few degrees, down all the way, or leave it at room temperature.

I said that I would leave it at the same temperature since I'm only leaving for a half hour or so, so by the time I come back the temperature would not have changed much. I should not lower it or higher it because it would be less fuel-efficient and take more energy from the heater to reach the new temperature level.

Any suggestions?
Thanks much, Sharon.

Ive heard on the news that you should keep it on, that it actually takes less energy that having to reheat your house. Also close your blinds.

sorry I am not much help, its all i know...
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Figure 1 Overall Structure Diagram Figure 2: Top view of the piston when it is cylindrical A circular opening is created at a height of 5 meters above the water surface. Inside this opening is a sleeve-type piston with a cross-sectional area of 1 square meter. The piston is pulled to the right at a constant speed. The pulling force is（Figure 2）： F = ρshg = 1000 × 1 × 5 × 10 = 50,000 N. Figure 3: Modifying the structure to incorporate a fixed internal piston When I modify the piston...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
