The table shows the same data about how the temperature of each greenhouse changed over 2hours.

Question

Greenhouse Initial temperature (°C) Final temperature (°C)
Greenhouse with solar panels 7 21
Greenhouse with no solar panels 7 22
Which statement is correct?

A.thermal energy was transferred more quickly into the greenhouse with solar panels
B.thermal energy was transferred more quickly into the greenhouse with no solar panels
C.thermal energy was transferred into both greenhouses at the same rate

Answer 1

To determine which statement is correct, we can analyze the temperature changes for both greenhouses over the same period.

1. Greenhouse with solar panels:

   • Initial temperature: 7°C
   • Final temperature: 21°C
   • Temperature increase: 21°C - 7°C = 14°C

2. Greenhouse with no solar panels:

   • Initial temperature: 7°C
   • Final temperature: 22°C
   • Temperature increase: 22°C - 7°C = 15°C

In this comparison, the greenhouse with solar panels had a temperature increase of 14°C, while the greenhouse without solar panels had a temperature increase of 15°C.

Since the greenhouse without solar panels achieved a slightly higher temperature gain (15°C compared to 14°C), we can conclude that:

B. thermal energy was transferred more quickly into the greenhouse with no solar panels.
