Thanks for the reply. Yes. The results were almost the same.

Aim: How does the volume of water at a given temperature affect the amount of ice that can melt in it? I did a lab experiment. I put ice in different volumes of water and waited for 5minutes. I measured the amount of ice melted and the final temperature of water. RESULT: (starting...

OHH YES. Thank you so much.

I realized that I need to investigate the resistance in a lamp. But I calculated the resistance of the variable resistor. Does this mean that the resistance of the lamp decreases? (because the resistance of variable resistor increases). Sorry, I am really really confused.

OHHH does that mean as the filament gets hotter, there is more resistance?

Thanks for the posts. The results I got are: 1.6V, 160mA=10ohms at the dimmest lamp 1.9V, 180mA=10.6ohms 2.4V, 210mA=11.4ohms at the brightest lamp What I don't get it that when they are dimmer, I thought it should have more resistance (Volt), but it has the most Ω when it has the...
